Use the “passwords” feature to check if one of yours is compromised. If it shows up, never ever reuse those credentials. They’ll be baked into thousands of botnets etc. and be forevermore part of automated break-in attempts until one randomly succeeds.
I was thinking about this earlier. The password manager browser plugin I use (Proton Pass) defaults to staying unlocked for the entire browser session. If someone physically gained access to my PC while my password manager was unlocked, they’d be able to access absolutely every password I have. I changed the behavior to auto-lock and ask for a 6-digit PIN, but I’m guessing it wouldn’t take an impractical amount of time to brute-force a 6-digit PIN.
Before I started use a password manager, I’d use maybe 3-4 passwords for different “risks,” (bank, email, shopping, stupid shit that made me sign up, etc). Not really sure if a password manager is better (guess it depends on the “threat” you’re worried about).
Edit: Also on my phone, it just unlocks with a fingerprint, and I think law enforcement are allowed to force you to biometrically unlock stuff (or can unlock with fingerprints they have on file).
If someone can gain physical access to your PC you are done anyway, he van simply copy the file or do whatwver he want
