Canvas detection guide

Can Canvas detect cheating?

Last verified: 2026-09-25 · Checked against Instructure, Respondus and Honorlock documentation

Short answer

No. Canvas does not detect cheating on its own, and it sends your instructor no alert.

  • It keeps a quiz log: when you view and answer questions, and when you leave the quiz page and come back.
  • The log never names the tab or app you went to.
  • Canvas cannot see your screen, your phone, your extensions or your clipboard.
  • Proctoring tools such as LockDown Browser or Honorlock see and block much more.

Our pickCanvas Quiz Solver shows the answer right below each question, inside the quiz page. No second tab, so there is no page switch for the quiz log to record.

What can professors see on Canvas during a quiz?

During a quiz, your professor can see the quiz log for your attempt: when it started, which questions you viewed and answered, and each time you stopped viewing the quiz page and resumed it. They also see your answers, your score, and the course activity data that Canvas keeps for every student. They cannot see where you went when you left the page. In New Quizzes, the client IP address shows in the change log for the attempt, and only "admins and instructors with the View the Client IP address permission" can see it (Moderate page guide, Canvas permission reference). When the instructor turns on Detect Multiple Sessions, multi-session details add the client IP, browser session ID, browser, and operating system of each session, and those "can only be viewed by admins" (Instructure multi-session details guide).

This page is the overview. Each topic below has its own detailed guide, and all of them are listed on the Canvas detection guides page.

Can professors tell if you cheat on Canvas?

Not from a Canvas alert, because Canvas sends none. Nothing in Canvas marks an attempt as suspicious or gives it a cheating score. A professor who wants to check opens the log by hand, one student at a time: Options, then Show Student Quiz Results, then the student, then View Log (Instructure quiz log guide). When you have several attempts, the log opens on the most recent one. In New Quizzes the same kind of record is on the Moderate page, where View Log lists each event, the elapsed time, and the moments you stopped and resumed the quiz (Moderate page guide).

What the professor reads there is timing, not intent. Instructure writes that "quiz logs are not intended to validate academic integrity or identify cheating for a quiz", and the New Quizzes guide repeats that the log should not be used to validate academic integrity. A professor can still draw their own conclusions from a pattern in the log, and your school sets its own integrity rules. The log is one input to a human judgment, not a verdict.

Is the quiz log always on?

Not necessarily. Instructure's quiz log guide says that "Quiz Log Auditing is currently a course opt-in feature", so the Classic Quizzes log depends on that feature being turned on for the course (Instructure quiz log guide). The guide does not say who turns it on at a given school. The same page sets three more limits:

  • Six months. "Quiz logs are only retained for six months." An older attempt may have no log left to open.
  • Autosave errors. The log "does not include an accurate log for Fill-in-Multiple-Blanks, Matching, Multiple Answers, and Multiple Dropdown questions". Autosave can make those questions look answered at the very start of the attempt.
  • One attempt at a time. The log starts when you begin the quiz and covers that attempt only.

New Quizzes keeps its own event list on the Moderate page, and the opt-in note above is written for the Classic log.

Does Canvas detect tab switching?

Yes, in the sense that the Classic quiz log writes "Stopped viewing the Canvas quiz-taking page" when you leave the quiz, and "Resumed" when you come back. Instructure lists the triggers as when a student "closes the browser tab, opens a new browser tab, or navigates to a different program" (Instructure quiz log guide). The record says that you left, never where you went. In the Canvas API these entries are page_blurred and page_focused events, and their event_data field is null, so no tab name or URL is stored (Canvas quiz submission events API).

Other things can take the page out of view too. The browser event behind this reports only that the page became hidden or visible (MDN visibilitychange), so a notification you click or a locked screen can write the same line as a real tab switch. For every trigger and the false alarms, read our guide to whether Canvas detects tab switching.

Will Canvas know if I split screen?

Not from the split layout itself: Canvas does not see your window size or what sits next to the quiz. It sees focus. In split screen the quiz page stays visible, so the tab is never hidden. But Instructure counts navigating "to a different program" as a trigger, and the API calls the event a blur, which is the browser's word for losing focus. So a click into the other window can write Stopped viewing while the quiz is still on screen. Instructure's guide does not describe split screen directly, so treat that as the likely behaviour, not a documented rule.

Proctoring changes this. The Honorlock extension can "detect window resizing" when its BrowserGuard setting is on (Honorlock extension permissions), and Honorlock can "require test takers to use only a single screen" (Honorlock FAQ). LockDown Browser turns off task switching for the whole attempt. More detail is in the section on whether Canvas detects split screen.

What is the 15 second rule on Canvas?

It is a figure from a Canvas Community forum answer, not a rule from Instructure. In a forum thread, a user quotes a "Community Champion" who wrote that the entry "can occur" after more than 30 seconds of inactivity inside Canvas, or after clicking out of the quiz for more than 15 seconds. That answer says the entry can occur after that time, not that it occurs only after it. Repeated on many sites since, it is where the 15 and 30 second numbers come from (Instructure Community forum thread).

Instructure's own quiz log guide gives no time threshold at all. It lists what triggers Stopped viewing and says nothing about how long you have to be away. We found the number in no Instructure document, so do not rely on it. The safe reading of the official guide is that leaving the quiz page can be recorded, however short the visit.

Can Canvas detect your phone?

No, Canvas has no way to see a phone that sits next to your computer. It is a website, and it records only what happens on its own pages. Two cases are worth knowing:

  • The same quiz on two devices. Opening a New Quizzes quiz on your phone while it is open on your laptop creates a second session. When the instructor turns on Detect Multiple Sessions, "students receive a notification if they attempt to continue a quiz in a different session" (New Quizzes settings). Admins can then view the client IP, browser session ID, browser, and operating system of each session. Without that setting, multi-session activity is not recorded.
  • The Canvas Student app. You can take Classic and New Quizzes in the app on iOS and Android. Instructure documents no logging rule that is specific to the app.

Proctoring is again the exception. Honorlock says it can detect cell phones and other devices: its product page lists flags for visible phones and other handheld devices, detection of Apple devices nearby, and alerts on voice commands such as "Hey Siri" (Honorlock cell phone detection). If the school asks for it, Honorlock also makes "a webcam video recording that includes your desktop activity and audio recording" (Honorlock FAQ).

Does Canvas detect Chrome extensions?

No. A web page cannot list the extensions in your browser. Extension content scripts run in an isolated world, so the page sees the DOM changes an extension makes and nothing else (Chrome content script docs). Canvas has no extension scanner, and the quiz log has no field for one. Proctoring tools are where this changes. LockDown Browser is a separate browser that loads no Chrome extensions, and the Honorlock extension can "disable extensions after consent from the user for the duration of the exam". Honorlock adds that it does "not re-enable the extensions" when the exam ends, so you turn them back on yourself. The long version is in our guide to Chrome extension detection.

Can Canvas detect ChatGPT?

Not by itself: Canvas ships no AI detector. Schools can add tools such as Turnitin as plug-ins, and those scan long-form writing that you submit, such as essays (Turnitin AI writing detection model). They do not read a multiple-choice selection, and the quiz log records that you answered a question, never where the answer came from.

Where a detector does run, its score is a signal, not proof. Turnitin says AI scores from 0 to 19% carry a higher rate of false positives, and that the score "should not be used as the sole basis for adverse actions" (Turnitin AI Writing Report guide). More in our guide to AI detection on Canvas.

Can Canvas detect copy and paste?

No, clipboard events are not in the Canvas quiz log. The log holds four kinds of event, and none of them is a paste (Instructure quiz log guide). Instructure documents no clipboard tracking anywhere else either. The indirect signal is focus: if you switch to another window to copy something, the log records that you stopped viewing the page. Text you submit in an essay can still go to a similarity checker. Inside LockDown Browser, "copying and pasting anything to or from an assessment is prevented", and Honorlock can block copy and paste as well. Detail in our guide to copy and paste on Canvas.

What does the Canvas quiz log show?

The log is a timestamped list for one attempt: viewed a question, answered a question, stopped viewing, resumed. It holds no screen image, no keystrokes, and no tab name. The API behind it also records events such as question_answered and question_flagged, which is how a flagged question shows up. Instructure keeps these logs for six months, and its guide is the source for every limit named above (Instructure quiz log guide). Read a log line by line, with what each entry means, in our guide to the Canvas quiz log.

Canvas Quiz Solver puts the answer right below the question, inside the Canvas quiz page. You do not open a second tab, you do not copy the question into ChatGPT, and you do not switch windows, so there is no page switch for the quiz log to record. It works on Classic Quizzes and New Quizzes, and you can start free. Add Canvas Quiz Solver to Chrome.

Can Canvas see your screen, webcam, or screenshots?

No. A page in your browser cannot photograph your desktop, read another tab, or switch on your camera or microphone on its own. Screen capture and camera access sit behind a browser permission prompt that you have to accept (Screen Capture API, getUserMedia). Canvas asks for neither during a quiz. Instructure documents no screenshot detection, and the quiz log has no event type for one. If something does ask for your camera or screen, it is a proctoring add-on your school installed. In LockDown Browser, "printing and screen capture functions are disabled".

For screenshots alone, the full answer is can Canvas see if you screenshot: what the quiz log records instead, device by device, and on proctored exams.

What do proctoring tools add to Canvas?

A proctoring tool adds what Canvas lacks: it can block other apps, record your screen and camera, and control your browser. Your school chooses whether to use one, and the quiz instructions or the assignment page will say so.

Respondus LockDown Browser

LockDown Browser is a separate browser, not Chrome, and a quiz set up for it cannot be opened in any other browser (Respondus LockDown Browser). For the length of the attempt it:

  • prevents access to other applications, including messaging, screen sharing, virtual machines, and remote desktops
  • disables printing and screen capture
  • prevents copying and pasting to or from the assessment
  • disables the right-click menu, function keys, keyboard shortcuts, and task switching

Chrome extensions never load in it.

Respondus Monitor

Respondus Monitor is the webcam product from the same company. In Respondus's words, "Students use a webcam to record themselves during an online exam", and afterward "flagged events and proctoring results are available to the instructor for further review" (Respondus Monitor).

Honorlock

Honorlock runs as a Chrome extension during the exam. Its FAQ also describes a desktop Honorlock Application, in limited release, that is "designed to detect any apps on your device that you may use (or attempt to use) during the exam". According to its own documentation, Honorlock can:

  • disable your other extensions after you consent, for the duration of the exam
  • close tabs that are already open, or block new ones, when BrowserGuard is on
  • block copy and paste
  • detect window resizing, and require a single screen
  • record your webcam, your desktop activity, and audio
  • detect cell phones and other devices

Canvas quiz settings

The settings built into Canvas are milder: shuffled questions, a time limit, an access code, limits on going back to earlier questions, an IP filter, and Detect Multiple Sessions (New Quizzes settings). None of those watch your machine.

The way to get answers without leaving the quiz

The quiz log records each time you leave the quiz page. Canvas Quiz Solver puts the answer right below the question, inside the Canvas quiz page. You do not open a second tab, you do not copy the question into ChatGPT, and you do not switch windows, so there is no page switch for the quiz log to record. A web page cannot list the Chrome extensions you have installed. It works on Classic Quizzes and New Quizzes, and you can start free, then it costs $14.99 a month. AI answers can be wrong, so check them against your course material.

It does not run inside LockDown Browser, and Honorlock can turn Chrome extensions off during a proctored exam. If you are comparing tools, read our Canvas Hack extension review.

Detailed guides for each question

Each guide below takes one of the questions on this page and goes deeper, with the full source list.

Common questions

Can professors tell if you cheat on Canvas?

Canvas gives them no cheating flag. A professor can open your quiz log and see when you answered each question and when you left the quiz page, but the log does not say where you went or where an answer came from, and Instructure says it is not meant to identify cheating.

Can Canvas detect if I switch tabs?

Canvas can record that you left. Opening or switching to another tab writes a Stopped viewing entry in the Classic quiz log, and coming back writes Resumed. The entry never names the other tab.

Will Canvas know if I split screen?

Canvas cannot see your screen layout. It can log a focus loss when you click into the other window, because Instructure counts moving to a different program as a trigger. Proctoring tools such as Honorlock can detect window resizing and require a single screen.

What is the 15 second rule on Canvas?

It is a number from a Canvas Community forum answer, not from Instructure. The official quiz log guide lists what triggers a Stopped viewing entry and gives no minimum time away, so do not count on a grace period.

How to cheat on Canvas without being detected?

Know what Canvas records first. The quiz log writes Stopped viewing each time you leave the quiz page, it keeps the timing of every answer, and in New Quizzes the client IP shows in the change log for admins and permitted instructors. Canvas Quiz Solver puts the answer right below the question, inside the quiz page, so you do not switch tabs and there is no page switch for the log to record. Your answers and their timing are still in the log. It does not run inside LockDown Browser, and Honorlock can turn Chrome extensions off during a proctored exam.

Does Canvas track you outside quizzes?

Inside Canvas, yes. The People page shows Last Activity and Total Activity, and the course Access Report lists what you viewed, how often, and when. Outside Canvas it sees nothing. Other sites, other tabs, and other apps are not part of any Canvas report.

Can Canvas see your screen?

No. Capturing your screen needs a browser permission prompt that you accept first, and Canvas never asks for one during a quiz. A proctoring tool your school adds is a separate program with its own permissions.

Does Canvas record you?

Canvas has no built-in webcam or microphone recording. Proctoring add-ons do: Respondus Monitor has students record themselves on webcam, and Honorlock records webcam video, desktop activity, and audio. Your school has to add them, and you see the setup before the quiz starts.

Can Canvas see your IP address?

In New Quizzes, the client IP address appears in the change log for your attempt, and only admins and instructors with the View the Client IP address permission can see it. When the instructor turns on Detect Multiple Sessions, multi-session details also show the client IP, browser, and operating system of each session, and only admins can view those.

Is the quiz log enough to prove cheating?

Instructure says quiz logs are not intended to validate academic integrity or identify cheating. The log shows timing and focus loss, and focus loss has ordinary causes such as a notification you clicked. Autosave can also make some question types look answered too early.
