Test plan

STR (fresh profile) — e.g. with Beta:

1. Launch Brave
2. go to brave://password-manager/passwords
3. add two passwords:
   • password 1 (can be any site; aaaaa.com for example)
     • Site: aaaaa.com
     • Username: aaaaa
     • Password: aaaaa
   • password 2 (can be any site; bbbbb.com for example)
     • Site: bbbbb.com
     • Username: bbbbb
     • Password: bbbbb
4. close the browser
5. open %LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\Login Data in DB Browser for SQLite
6. go to Execute SQL
7. paste UPDATE logins SET password_value = x'7631301f2bb0cc71024cedf754d0992d32' WHERE username_value='aaaaa', hit F5 and then Ctrl + S
8. Launch Brave - you'll notice that both passwords are not being listed via brave://password-manager/passwords
9. enable Brave Sync via brave://settings/braveSync (don't need to pair a device/just enable Sync)
10. once Sync has been enabled, ensured that Password is enabled via brave://settings/braveSync/setup
11. restart the browser and you'll notice that the decryptable are now being listed
