It is disabled with Advanced Protection as well, iirc.

Do you have 2fa enabled? It is possible that you can't generate app-specific passwords whithout 2fa enabled.

I'm pretty sure it's because you forgot to fill out the two dropdown fields, "Select the app and device you want to generate the app password for."

If you don't fill those out, the button to generate the password is grayed out.

No problems here. Have 2fa set up and everything.

I just generated one with that link.

Works for me.

Still works for me.
