Passkey Confusion

[TxDoc]

I'm trying to use a passkey instead of needing to be around my tablet or backup Wi-Fi phone. But, it's not going well.

When I tried it, it said no passkey set up yet. When I go into that account's security settings and passkey... It says I have several, but haven't used them.

I can't see them. And, I can't setup a new one or delete the ones it states I already have, but have not used. ????

I don't know what to do next.
Any advice or suggestions are GREATLY appreciated
Thank you

I found out I can't use DuckDuck Go browser to make a passkey and when I go into the account to make a new passkey and click on make a passkey, I get the error message attached.
