I'm really frustrated with my Apple ID right now. I've got an iPhone 11 Pro Max that I don't use much anymore, and it's still signed into my Apple ID without any issues. I've also got an Apple TV 4K that I sign in and out of without a hitch. However, things went haywire a few days ago when I tried to set up my partner's iPad (the basic 9th gen model). I did a factory reset on the iPad, disabled iCloud, and set it up as new, but I kept getting a 'Verification failed' message when trying to sign in with my Apple ID. I double-checked my login details on other devices, and they worked fine there. I even reset the iPad multiple times and eventually got it to log in, but then I faced the same issue when trying to set up a new Apple TV 4K. I tried using the iPad to connect, but it kept asking for my Apple ID password and failed again. I even tried my iPhone, which has had no issues until now, and got the same 'Verification failed'. I've changed my Apple ID password, but that didn't help. What could be causing this?

Definitely give a different network a try. Since you've logged in fine through the browser, the issue might just be with your current connection. Switching WiFi might help!
It sounds like your IP address might be causing some problems. Sometimes if you attempt to log in too many times, it can trigger a temporary block. Have you tried using a different WiFi network to sign in? That could be worth a shot!
I doubt that's the issue, though. I'm able to log into my Apple account via a browser without any problems.

I already tried that and it didn't work. Still got the same 'verification failed' message.
