A newly disclosed privacy vulnerability in Apple’s Hide My Email feature can reportedly allow an attacker to uncover the real email address behind a generated alias. According to the researcher who found the bug, it was responsibly disclosed to Apple more than a year ago but remains unpatched, and independent testing has verified the issue.



Just get a cheap domain and configure a catch-all redirect. Obviously not a solution viable for normies, but should be easy for many Lemmy users.
Almost every website will accept a custom email domain
It depends on the domain. I intentionally have a bizarre .party domain I use as a shibboleth to see if a company is worth using. If they don’t have a way to use my .party email, I assume they are lazily run and based their decisions either on outdated nonsense or are a gross data mining operation I should avoid anyway.
At least my .club domain worked for everything except deepseek so far
