Please allow PIN unlock in 1P8 Android

I also have Pixel phones (PIN unlock), and a Samsung Tablet with no biometric option and two Windows PC's with "Hello" Pin established.. I"m still in a trial period, coming from LastPass, and find PIN unlock on Windows (Hello) is good, but am required to re-enter Password in the App at what seems random situations. I'm unable to figure out why, but add I'm flipping between devices with 1PW installed.

It would be real nice to have a PIN unlock capability, even it it requires a minimum number of characters. I will add that once you get comfortable with how 1PW works in the Windows and Android environment i'm comfortable that the product matches usability of LP; and I'm satisfied the underlying security is better(?).

Again, my vote for PIN unlock, a 20 plus word/symbol/number master password on frequent logons when the devices are being used in an environment with good physically security is a tad frustrating.
