A relative used my laptop and I realized several accounts stayed signed in. No known misuse yet. Sensible hardening steps that are not overkill?
Shared family device left accounts signed in

Sign out everywhere where available, change passwords for high-value accounts, and use separate browser profiles for shared machines.
Review active sessions in each major account. It is tedious and worth it.
I moved to a password manager so I stop reusing anything on shared devices.
