When I was about 15 I created a list of eight character, randomly generated passwords. I memorized about 10 of them and to this day different combinations have been used for things like disk encryption, Apple ID, etc. I use a password manager for just about everything but there are a few things where knowing your password is a must, so brute-force memorization can be the way to go.
For what it’s worth, only one of the passwords was in a data leak before I started combining them. It happened to be a weaker password anyway (no mixed case) so I use it sparingly for low-priority offline stuff.
20 characters or more

Fortunately you’re an adult now and know about password managers. Only memorize one password. Generate the rest.
