Thanks to all of you who gave me guidance in the thread about password managers. It got me thinking I should expand the question to overall best practices regarding security, just in case I have any other important blind spots.

What are the essential do's and don'ts of digital security for the average person?

I feel like it's impossible to remember passwords that are long, random, and unique for every service. I have too many accounts.

On the other hand, I don't like the idea of giving up control of my passwords to a password manager and using the ones it generates and stores. It feels weird that I wouldn't "know" my passwords.

Is this a hangup I should just get past? What do I do if I need to login somewhere but cannot access my password manager?
