Password issue MacBook Air M1

[Zapdoc]

Need to enter password twice to start up my new MBA M1 although sometimes only once is enough -
This is another issue not sure how important but I am getting concerned there may be a more sero=ious issue ahead after 14 day return period.
Its a fully spaced 2020 MBA M1 16 GB and 2TB

any advice please

Do you have FileVault enabled?

I run Mojave with multiple user accounts enabled. Whenever I select a user from the macOS login screen, my machine will erase any password or partial password typed in the text box before a few seconds have passed. This causes the login to fail and I have to re-login. It might be related to a Time Machine drive spinning up and "distracting" the OS...in any case, if I wait 5 seconds or so before entering a password and logging in, everything works as expected.

Apple_Robert is right this is normal behavior if you have your disk encrypted.

Protect data on your Mac with FileVault

Turn on FileVault to add an extra layer of security to the encrypted data on your Mac.

When your Mac is shut down completely, the first password will unencrypt your drive, second will login to your account.

Just checked and yes it is enabled - would I be better turning off FileVault ?

would I be better turning off FileVault

Only if there is nothing on your computer worth protecting from loss or theft.

On Mojave at least, FileVault doesn't require a double login after booting or waking from sleep. As long as I wait for my Time Machine drive to spin up, a single login is all it takes to access any user account on my Mac.
