I’ve started using 12-16 character passwords, randomly generated by Lastpass. I used to use the same password, plus a unique couple characters at the end, but that leads a would-be attacker to know my system, if he ever got hold of a couple of them. So I don’t do that any more. And manually entering 12-16 character passwords, whether just once or several times, really isn’t fun, especially with random characters, including special characters, not just numbers and letters. Lastpass will autofill the password based on the URL, or give you the option to select from multiple username/password pairs if you have them (say you have multiple email accounts with Google). Even on mobile!
I always have my phone with me, so I always have access to any site or app. And with 2FA, you get another layer of security. I actually don’t want to think about life without a password manager.
