alt Hacker NewsCan you cite an example of a big, well-known, etc service that enforces a 'you can't change your email address' rule? I haven't really seen this sort of thing in the wild to be honest. Maybe one or two over 20+ years? I think the norm is using a username or an internal identification number (such as an UUID). It is rare the email address is actually used as the primary key to identify an account.

My hospital.
Yeah, and they insist on using it for MFA.
Actually the tech support did change what I use to sign in, but the patient record/profile is separate, and not user-serviceable.
I tried twice to change it, but they were able to send me on epic bureaucratic fools errands; I had to give up!

Philips Hue.
I've run into others, but that one sticks out because it's the only account I still have using my old email, since creating a new account would also involve re-pairing all of my Hue products.
