If you still get the 2FA error, without having the 2fa_required configuration, then you set up a 2nd factor, eg. time based one time password / Google authenticator.
You can either disable all 2FA:
REPLACE INTO egw_config (config_app,config_name,config_value) VALUES ('phpgwapi', '2fa_required', 'disabled')
Or you can deleted the 2nd factors:
DELETE FROM egw_ea_credentials WHERE cred_type=32
