iCloud website asking for MacBook password

Every time I go to iCloud.com I get this popup asking me to log if I want to continue as (my primary iCloud connected to computer) but then when I hit continue I have to enter username for my computer. this only happened recently. and now after that when I go to log in and lets say I use private browsing and apple send me a code to put in, the code used to just automatically enter itself after pressing okay but now I have to enter it manually. Anybody else having this issue?
