So many services don't support changing your username. This sucks if you use your full name as a username, then happen to change it... which isn't exactly uncommon.
I've got a sneaky suspicion if dev teams had better gender balance this wouldn't be the case :\
Yup. I automatically spec things so that users are assigned random unique primary keys. On occasion I have allowed multiple (globally unique) usernames per user.
I used to do sequential user ID assignment, but changed to random to reduce information leakage.
I even know a service that doesn't even let you change your email address. Need to change? Create a new account.
@caius Meh. I'd probably hit 'em with a GDPR request to delete the old one, explaining why. That might help prioritise changing email as a feature :)
