Using a password manager and 2fa has been a boon for me.
As long as it's not Lastpass. Still trying to work may way through changing all my details. Jesus there are some broken websites out there. Some have no password changing method (unless you say you have forgotten it), others you can change the password, get an email to say it has been changed, but it still lets you login using the old details in a private window!
. On a serious note, I've had to use a password manager as it gets ridiculous, last time I check I had over 100 different logins stored. I always enable 2FA where possible, weirdly a guy I work with hates it as its inconvenient, but for the sake of security I think it's worth it.
