2 | | -Locked Mode X is a simple bypass for Google's locked mode! It works as of September 8th 2025 in chromeOS v139. <br> |
3 | | -**THEY WILL NOT FIX THIS EXPLOIT. I TRIED GETTING GOOGLE TO DO SO BUT THEY CLOSED MY ISSUE.** |
| 1 | +# locked-mode-bug |
| 2 | +This is a bug with Google Forms Locked Mode that lets you exit Locked Mode without actually exiting the form itself. It works on ChromeOS version 139 and has been functional since at least version 131. There’s a good chance it works on all ChromeOS versions that support Locked Mode. |

5 | | -## Discovery: |
6 | | -- In Economics, I had a quiz in locked mode. After I did it, I decided to make my own locked mode quiz and try some things to escape it. |
7 | | -- After a while, I found the exploit below... |
| 4 | +# Instructions: |
| 5 | +- Open two windows of the locked form in question. |
| 6 | +- Click the Continue button on both pages at the *exact* same time. If you are too late, it will lock you as normal. |
| 7 | +>This exploit is likely possible on touchscreen Chromebooks only due to how fast you need to be to click both buttons. |
| 8 | +- You should be in locked mode now, but it will only show a blank window with a forms icon at the top left. Click it. |
| 9 | +- It should now show the enter locked mode screen on the form when you're already in locked mode. Click Continue. |
| 10 | +- Click the overview button on your keyboard. You'll be able to see all the windows, and hence "exit" locked mode. However, you can still return to the form and complete it. |

9 | | -## Instructions: |
10 | | -1. Open two windows of the locked form. |
11 | | -2. Click both of their continue buttons at the EXACT same time. Too late and it'll work as normal. <br> |
12 | | - You should practise first by creating your own locked forms and previewing them. <br> |
13 | | - This exploit is probably only possible on touch screen due to how quick you need to be. <br> |
14 | | -4. You should be in locked mode now, but it will only show a blank window with a forms icon at the bottom left. Click it. |
15 | | -5. It should now show the enter locked mode screen on the form when you're already in locked mode. Click continue. |
16 | | -6. Click the overview button on your keyboard. You'll be able to see all the windows, and hence "exit" locked mode. However, you can still return to the form and complete it. |
| 12 | +# Notes: |
| 13 | +- I reported this to Google, but they declined to make a fix. If you try this, you do so at your own risk; I accept no responsibility for any consequences. |
| 14 | +- You might notice that locked mode is an app called Assessment Assistant (https://chromewebstore.google.com/detail/assessment-assistant-dev/ibnfdimnablpmgpmgegnbdadookdffie). |
| 15 | +- Alt-tab closes the quiz - use the window view button! |
| 16 | +- You cannot screenshot until you complete/exit the form properly ('submit' or 'close quiz')! |

19 | | -- You cannot screenshot until you complete the form properly ('submit' or 'close quiz')! <br> |
20 | | -- Alt-tab closes the quiz, use the window view button! <br> |
21 | | -- This is very buggy! <br> |
22 | | -- You might notice that locked mode is an app called Assessment Assistant (https://chromewebstore.google.com/detail/assessment-assistant-dev/ibnfdimnablpmgpmgegnbdadookdffie) <br> |
23 | | -- GOOGLE UPDATED GOOGLE FORMS AND NOW LOCKED MODE DOESN'T WORK WITH NEW PREVIEWED FORMS. IT WILL STILL WORK ON OLD FORMS. <br> |
24 | | -- You can still perform this exploit by Publishing the form and copying the link. <br> |
25 | | -- I don't care about what you do with this exploit since apparently this bug was too minor for Google to bother to fix it when I asked them. <br> |

| 18 | +You can practice this glitch by creating your own locked mode form, publishing it, and copying its link. |
| 19 | +It used to be easier when previewing a locked mode form behaved like the real locked mode. |
