Windows encrypted password and data store (DPAPI)
-
Most users do not know hat Windows uses a unique user master key (GUID) for encryption of logins and other secure storage data.
This thread is only for experienced users who want to get special information about storage of Windows encryption keys and encrypted browser login database.
If you have issues in Vivaldi to store passwords or password usage or Sync then open a thread in Support & Troubleshooting
Copying login database for Vivaldi and other Chromium-like browsers for a restore after installing a new Windows on a new PC or new Windows user account does not give them back a readable login database.
Some information on Windows Data Protection API:
- You Cannot Access DPAPI Confidential Information After Reinstalling Windows on a Stand-Alone Computer
- Windows Data Protection
- How to recover a Vault corrupted by lost DPAPI keys
- Recover Windows User Account Credentials
- DPAPI Secrets

Good stuff - make it a sticky?
Maybe add information about how users can migrate their passwords to a new system.
- Enable Vivaldi Sync and sync passwords to the new machine (recommended).
- Export passwords from
chrome://settings/passwords
and import on new machine.

Yes. But it should be updated, and then linked from here. That page is hidden under tips&tricks for all platforms, and this page is very Windows-specific.
Also note that the password import/export is now gone from the list of flags, but the options are there at least for me so maybe they made it default.
