I've added 2FA. I'm trying to figure out why it was compromised. Could it be because I installed an unofficial app on my device?
Is it really secure after adding 2FA?
what do u mean by installed unofficial app?
did u download gmail from the google store or some third party?
because that is usually the culprit
only use gmail provided by the google store or use a browser to login
and have 2fa enabled
i don't think linking other sites compromises the securite of your email
it is same as signing up with them and they get only name and email address linked to that account
