I can't believe that dad actually has more than 5 email accounts or so on multiple different platforms, while I only have 1 email account that I mainly use (the rest are email aliases, if only they existed back then) 

 Is Hotmail still even a thing nowadays? 

 ...and he doesn't use a password manager (yet), so how the heck he remembers all the accounts with quite complex passwords?

even I can't do that just for my master password
