I’ve been using a password manager for years, and.I’d be lost without it, but honestly I think this is a temporary solution. What I want to see is a no password future, and just use the code given by your MFA app. Forget having a password at all. Interestingly Microsoft has been pushing for this and you can already drop passwords for personal 365 stuff I think.
I have the ring doorbell and a home blob which I only use to play the doorbell tune in the house. It is 50/50 luck if the tune plays when someone presses the doorbell button.
