My mom would use the same password for everything or she would mix it up a little tiny bit.
Her passwords were like.
Rainbow2002!
rainbow2003
RAINBOW!!!
It was a different word from rainbow, but that’s just an example.
I got her using two factor with Google with a really good password and she’s using the built-in Google password manager. Now all of her passwords are 20+ random strings instead of a single word with different numbers at the end.
I think that’s a much better system than what she was using before.
Facebook doesn’t use e2e.
There is a private chat e2e feature, but then your chats don’t show up on PC.
