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