How to enable fingerprint for unlock upon startup?

How can I switch from password to fingerprint when restarting my phone?

I'm trying to secure my Android-phone, a Huawei P20 pro.

With some 200 passwords diviided between devices and webpages the only way to use the ones for my phone is to write them down and sticky them physically on the phone. With the passwords giving access to security-settings using these passwords to unlock my phone constitute a severe security breach. I need to disable them and preferably replace them with my fingerprint.

I've successfully removed my sim-lock password.

How can I switch from password to fingerprint when restarting my phone? The alternative is to not have a lock-screen at all. At least then I can protect my security-settings.

The quick answer is "no".

At the point the phone requests your pin the services needed to run the finger print login have not even been started.

Yes. In addition, Huawei released a new built-in feature for its phones in order for its users not to forget passwords. Every three days you have to unlock the phone with pin even if your fingerprint works fine.

Same with Samsung, I feel it's a great feature. A pain, but worth it.

Ironically, in light of your comment about requiring a PIN or password being "severe security breach", Google consider fingerprint to be weaker security than those (though stronger than pattern).

Improved security is the reason that Google give for their phones requiring PIN in addition to fingerprint every so often (it varies between every day and every other day, so I suspect it might be based on the number of times you unlock). Indeed with these other manufacturers doing this as well I wonder whether it's actually a feature of the android version rather than a manufacturer choice?

And of course fingerprint scanners can fail or be damaged, and we've had occasional reports of the stored prints being lost, so remembering the PIN or password as a backup is essential anyway.
