How can I log in again to ChatGPT Atlas?

How to log in to ChatGPT Atlas? Yesterday, I was thrilled to get Atlas. Then I noticed that I needed to block access to sensitive private information which was surprisingly easy to do but today my session has timed out and I can't get back in. I can't remember which email account I signed up with. To be honest, I can manage fine without ChatGPT Atlas plus it is scary and we have no comeback if private data is stolen. Apart from that, I was very impressed with it but, for me, the future is in the future.
