For single account migration you can use google playground to get a token,
https://developers.google.com/oauthplayground/
just make sure it has the right scope(s) to work. You need the "bearer token".
Then you can do
doveadm -o imapc_password=<token here> -o imapc_sasl_mechanism=xoauth2 ... sync

Dear Dovecot community,
I try to migrate a GMail mailbox to Dovecot using
doveadm backup -R imapc:. Since it seems that GMail disabled the login without XOAUTH2, I cannot figure out how to authenticate dovecot to GMail. Could you point me in the right direction? Thank you in advance!Best regards, Jan
Here the commands and config I am using:
