You can stop the login loop by deleting, moving, or renaming the duo-wordpress directory under the /plugins directory of your WordPress root on your WordPress hosting server. Depending on your hosting provider this may be something you can do through a shell, or through FTP, or you may need to place a support request to have it done.
We haven’t seen this compatibility issue with Birchpress before. We’d be happy to work with you more on getting to the root of the issue. If you’d like to work with us please email support@duosecurity.com or use the live chat at https://www.duosecurity.com/support, as these forums are not an official support channel.
Thanks,
Duo Security Support
Hi Duo Support,
Thank you for your response. I have 3 or 4 tickets submitted through support@duosecurity.com and no one ever responded. I also used live chat 2 or 3 times and they just referred me to support@duosecurity.com and kept on opening tickets for me.
