Hello everyone, I'm hoping to gain some insight regarding a privacy concern. I'm always mindful of the possibility that my biometric fingerprint, which I use regularly, could be accessed by someone if I were compelled to use it. For context, I'm not a criminal or particularly tech-savvy, and I'm relatively new to the world of privacy and FOSS applications. I currently use a Samsung phone. I've found that enabling Lockdown mode at night without needing to restart my device prevents anyone from accessing my phone while I sleep. However, my concern stems from a different scenario. Recently, while shopping, I experienced a sudden medical episode and lost consciousness for about ten minutes. During that time, shopkeepers assisted me. I'm worried that in such a vulnerable state, if someone were to misuse my biometric data, they could gain access to all my passwords and personal information, which feels unsafe. While I do value the convenience of biometrics, I'm seeking alternative solutions. Is there a way to prevent my phone from being opened using my fingerprint, even in urgent situations, without completely disabling biometric authentication? Thanks in advance.

This is well into paranoia territory. Anyone who is willing to either tail you until you have a medical episode or otherwise force the medical episode will have no trouble accessing your phone via more conventional means (kidnap + torture).

If you really want to protect against this "risk", either use a non-standard finger, or don't use biometrics at all.

And if you are likely to have a medical episode, either use your phones built in ICE (in case emergency) feature, wear one of those medical alert bands, or write the ICE numbers on your phone case.

Turn off biometrics and use a password. Problem solved.

Password instead of pin/visual pin/fingerprint/face id. That is it. Nobody can break in without a backdoor.

At US border, if you refuse to unlock your phone you are immediately put into custody. All this bullshit is suprisingly ineffective with a gun pointed at your head.
