So I've created a new gmail account because the name of the last one isn't exactly very professional. Anyway, I'm trying to have all my emails on the original address added to my current one but when I try to add it I'm given this message:
Server denied POP3 access for the given username and password. Server returned error: "[AUTH] Web login required: https://support.google.com/mail/bin/answer.py?answer=78754"
The support page isn't any help either. I know it's not a problem with my password because right when I tried to add the account my original account received an email saying a suspicious sign-in was prevented, from the IP 188.8.131.52, which just so happens to be situated in Mountain View, California.
