OK. You may have to try a few things, then.
Is it accurate that you do not have backups? If you have a backup (e.g., a recent vault export), then you’re not going to need to jump through the following hoops.
To attempt to recover data from the laptop, it is essential that Bitwarden is prevented from connecting to the internet (because this will cause your browser extension to log out, wiping all data). My recommendation would be to turn off your WiFi router before powering up the laptop. After powering up the laptop, immediately put it in Airplane mode (or otherwise disable internet connectivity).
Once the laptop is securely off-grid, you need to find the Bitwarden data folder. The location is different depending on which browser Bitwarden was used on, as explained in the documentation:
- Chrome:
~/Library/Application Support/Google/Chrome/Default/Local Extension Settings/nngceckbapebfimnlniiiahkandclblb - Firefox:
~/Library/Application Support/Firefox/Profiles/your_profile/storage/default/moz-extension+++[UUID]^userContextID=[integer] - Safari:
~/Library/Safari/Databases - Edge:
~/Library/Application Support/Microsoft Edge/Default/Extensions
The Chrome folder path may be slightly different if you are using a profile other than the default. For Firefox, you need the UUID value, which you can find by entering about:debugging#/runtime/this-firefox in the Firefox browser address bar.
Look for any file with a .json file extension in the above locations (especially a file named data.json) — except for Chrome, where the relevant files have the extension .log. I only have personal experience with the Chrome browser extension, so if you were using Bitwarden on a different browser, I will have to make some educated guesses about how to help you.
Let me know what you find.
