One of nightmares too! I have memorized many PINs and passwords and sometimes I got to mix them up. I also love Hive Keychain, it is very helpful in the blockchain. For my Passwords in Hive Keychain and Hive Signer I use a notebook to write them down !BBH
With too many passwords, we tend to mix them up. Sometimes I enter my Phantom wallet password to unlock my Metamask, haha! It's good to write them down so when memory fails, we have some back up :)

I suppose It's the best thing we can do ❤️
