The UK government is telling people that Russia is trying to hack into their personal email accounts and will get their passwords, so they all need to switch to biometric right now. In other words, give the UK government your face and fingerprints right now! Many people will, of course, fall for this.
Passwords suck, plain and simple. Passkeys are one of many better solutions, including local on-device biometrics protected by dedicated hardware.
Unless, of course, if the UK is suggesting some government-backed biometric system or app. “Send us your fingerprint, old chap. Then we’ll know which fingerprints aren’t yours.” That’d be a hard pass.
