  1. Where does Google save my screen lock password as it asks me to verify my Google account by entering it?
  2. That means Google knows my screen lock password.
  3. Where can I find that password in my Google account or from Google?

    Your password doesn't leave your device and therefore Google doesn't know that//Android has a key store mechanism to make it impossible for anyone to access it – beeshyams Nov 11 '22 at 16:23

    When does it ask to verify your Google account? Is it on "forgot my password"? – Andrew T. Nov 11 '22 at 16:49

    That could be the Google Factory Reset protection. Have you performed a factory reset using recovery menu? Android saves a hashed version of the Google account password to ensure you are the owner of the phone. – Robert Nov 11 '22 at 17:17
  • @AndrewT. when i try to login to my google/gmail account and i have activated two factor authentication i guess , so in many option "try another way" like it is asking me to verify that's it's my account by otp, or by screen lock password – Jimmi Nov 12 '22 at 06:53

While every app is different, and there is no general way to know for certain what data is being collected/transferred, a common practice is to use a hashed/seeded string of a password (instead of the password itself).

In this way, the password can be entered on your device, password is hashed/seeded, and only the hash is sent to a central server for comparison (the server also should only have the hashed/seeded string stored, and not the actual password).

When the hashed/seeded strings match, access is granted, as this indicates the original password was entered correctly.

This is not without its problems, but they are seldom realized in actuality.
