I got a small annoyingly weird problem with my 7,1. About half the time - more or less 50% - when I boot up, reboot nMP won't take my password. Highlights the type and shakes. I input it again and it's fine. I'm SUPER careful to do it correctly. Now whenever I have other reasons to put in the password there's never a problem. ONLY on reboot. And yesterday twice the password was not taken at all. I had to reboot to et it to work.

ANY IDEA WHAT THIS PROBLEM IS? I'm using the new wireless keyboard. I've tried it connected and not. No difference. OS? I have updated to 10.15.3. These problems occurred on 10.15.2. I haven't had the opportunity to see it yet on .3.
 
Have noticed an issue in Catalina with wireless keyboard where the first keystroke is not “registered” correctly. Solution I’ve used is to use the up arrow to select the user icon, then hit enter to bring up the password prompt. It might be a Bluetooth authentication issue, but cannot confirm. Does not happen with wired keyboard or built in with MBP16,1.

Try using an old Apple branded USB wired keyboard with your new MP7,1 and see if that improves the issue .

If it does , then your brand spanking new wireless keyboard is the problem . Probably a latency issue - bluetooth devices do have a slight lag .

Here's a trick - before you enter your password , hit the delete key a couple , three times on your wireless keyboard .

Here's a trick to see if it's the keyboard:
  1. Go to the login account in System Preferences -> Users & Groups.
  2. Unlock to make changes.
  3. Select Login Options.
  4. For "Display login window as" select "Name and password" instead of "List of users".
  5. Reboot.
  6. At the login screen enter the login name. See if characters are dropped.

Identical experience with a 2017 15” MacBook Pro. FileVault enabled. It must be a Catalina issue, since my machine is neither a Mac Pro nor am I using a wireless keyboard. Last time it happened I had to restart entirely.
 
I have this problem on 2009 Mac Pro 4.1 with 10.13.6 and Apple branded USB wired keyboard. It happens only after restart and I'm sure that typed password is correct. When I type it second time, the password is taken and I can login to macOS.
 
It happens on my iMac and the Mac Pro 7.1 on occassion
Have to have patience getting the first character registered correctly.
 
maybe try entering a few characters in the input field, then delete them, then enter the correct password
 
some users report 10.15.3 updates wreak havoc wireless connection. Since bluetooth emitted within same MIMO antenna below the handle, this might be root of problem
with your bluetooth keyboard.

Done all of that. Tried everything. Sometimes mine accepts the password on the second, third or fourth attempt. On one occasion it absolutely refused and had to be restarted.
 
I had it sometimes that the keyboard switches back to US means that z and y keys are messed up.
 
I resolved this issue by tapping twice the first letter (or number) of your pswwrd !
