It's also crazy that as far as technology has advanced, the concept of the username/password is still so prevalent. Passkeys are sort of changing things, it all still feels decidedly low-tech. Edit: Can you get a Yubikey as an RFID implant? ...asking for a friend.
Username/password is the easiest way to log in, assuming there is no stupid format requirements. It's just two strings stored in your password manager. The most retarded way to implement log in is actually magic email link, which requires opening your email client, waiting for the email to arrive, and copying the code. If you want to make it even worse, you can require that to be done using the same browser that is trying to log into the account.
What is really crazy is that things that should be just an application locally installed on the device (such as PowerPoint) need a login at all.
There's a secondary issue of schools pushing children to use proprietary applications when perfectly serviceable alternatives exist (especially for school level work).
How the hell we all normalized this crap is maddening.
