Most of my passwords are based around strings of characters that are comfortable to type, then committing them to muscle memory. There’s a few downsides to this:
If I need to log in to something on mobile and don’t have a proper keyboard with me, it’s tough to remember which symbols I’ve used
I share some of my logins with friends and family for certain things, if they call and need to re-enter a password, it’s usually impossible to recite it to them over the phone (most of my shared logins have reverted back to proper words and numbers to make it easier for the others)
If I lose an arm, I’ll probably have to reset all of my passwords.
But yeah, words alone provide plenty of possibilities. There’s a reason cryptocurrency wallets use them for seed phrases.
