If you use 2-factor authentication for your email account, you will need to make an additional setting to import your emails to BitsaboutMe.

Sign in with your email account and navigate to the security settings. There you should find in the login/password settings an option to generate app passwords. Create a seperate password for BitsaboutMe, which you can use to connect your email account to BitsaboutMe. Detailed instructions on how it works for Gmail can be found here.
