Passkey issue with IPad

I’m trying to use Sketchup on my IPad. The sign in starts the same as on my PC, asking for my email or user name, when I enter my password I get the attached sign in message:

I try to scan the QR code and it tells me that I don’t have any passkeys saved for this website or app. I have no idea how to use a security key.

I go to my account and try to set up a Passkey and it brings me back to this same page.
If anyone could help me get out of this loop it would be appreciated.

The passkey is created and kept on the PC.

On the PC, go to myprofile.trimble.com and manage your passkey there (either disable the current default or now create one on your iPad.
