So what's better, then? Tongueprint? I'm down to lick my phone to turn it on.

Tongue prints work fine on typical phone fingerprint readers, so it is an option.

I tried my noose tip and and tonge, neither worked (Huawei). Toes work (obviously).

People reported that pet's pawns work.

And you know this because you tried it? LOL :)

Actually, my father-in-law, which was pretty funny because he is typically quite reserved.

Iris scan is probably still our best bet, we just need better hardware and software.

How is the iris scanner on Microsoft phones in comparison?

People don't leave perfect moldae prints everywhere.

AFAIK CCC never had a proof of concept of a real world usage of this. They needed access the original finger.

That isn't to say it's not possible but it is a pretty major asterisk.

Didn't some group pull a politician's finger print off his dinner glass and then include it as an insert with all the issues of some magazine?

Can't find the reference right now, but somebody's gotta remember this, it was when the UK was considering using biometric data as IDs.

That was CCC in 2008. To underscore the inherent problems of biometric authentication, they pulled Wolfgang Schäuble's fingerprints of a dinner glass and published it in their magazine. That issue also included a ready-to-use replica. Schäuble was Germany's interior minister at the time and a strong proponent of biometric data in passports and increased surveillance.

They have done it with a fingerprint left on the device screen later on, if i remember correctly.

If I remember rightly that was a print applied to scanner glass, much less successful, and required absolutely perfect print transfer.

Which, imo, isn't much different conditions tbh (i.e. not representative of the real world)

Read the original ccc article or watch the video! They got the print off the phone itself. Only restriction is a high resolution scanner OR camera to capture it.

They did it also with a simple press photo of a politician.

There's no need to get a perfect copy.
