Reminder that "the cat is out of the bag" hits different when the cat deleted your passkey and now your dead grandmother's photos are gone forever. Great post on PRF misuse from @timcappalli -- https://blog.timcappalli.me/p/passkeys-prf-warning/ #passkeys
Please, please, please stop using passkeys for encrypting user data
Passkeys are the future of authentication, but using them for data encryption is a disaster waiting to happen. Overloading these credentials creates a dangerous blast radius that can lead to the irreversible loss of a user's most sacred memories and documents.
