Can't login iCloud on Big Sur MacBook 7,1

I just installed Big Sur on my 2010 MacBook on an external ssd as a test (internal ssd still has high sierra). I tried to login during the setup and it said my password or id was incorrect (it's not). I tried again manually in the settings and it still says my password is incorrect even when I copy paste. I logged in on iCloud.com through safari on the device and it does work. Why am I not able to log in?
