Fyi. I keep all my user names and passwords in an address book. A physical one.

In my house. That is locked. In a drawer. Not sitting on the computer or near it.

Someone would literally have to break in physically, find the address book, and then flip through it to even realize what it was.

I also have codes for some user accounts. So instead of writing them out I give myself a hint as to which one I used. I generally use a variation of 3 ones. With different slight changes.

For my bank account access and the email account associated with it I only have hints. Not an actual user or email. So it can't be bypassed with a password reset.

These are both unique though and neither are the same as each other nor anything similar to all the other user name variants I use for other accounts.
