I remember a case where a company decided to assign employees random 16 character passwords with symbols and rotated them every 90 days or so. They were unchangeable and the idea was that everyone would be forced to use a secure password that changed regularly.

You can probably guess what happened, and that was that no one remembered their passwords and people wrote it down on their pads or sticky notes instead.

Writing down a password is a great option. However you need to keep that paper in a secure location. Put it in your wallet and treat it like a $100 bill - don't paste it to a monitor or under the keyboard.

A password manager is better for most things, but you need to unlock the password manager somehow.

Also "app passwords". Not just change, you can't even append text to it.

Those are just API keys people can type.
