My ChatGPT account started showing inconsistent errors suggesting possible suspicious activity, even though I was the only person signed in at the time. As a precaution, I decided to strengthen my account’s security by enabling Advanced Account Security (passkey/security key sign-in).
However, after completing that setup, I was no longer able to sign in successfully using my passkey — even though the system correctly recognized both the passkey and my account. This forced me to begin the account recovery process, which requires a mandatory 48-hour waiting period after a valid recovery key is submitted.
In an attempt to work around the issue, I tried signing in through multiple channels: my main desktop computer, a secondary laptop, a smartphone, and a tablet, across different networks (home Wi-Fi and mobile data from different carriers) and different browsers (Chrome, Firefox, and Mozilla). Every single attempt resulted in the same session error, which rules out an isolated device, network, or browser issue.
Throughout these attempts, the system consistently returned the following errors:
- “Session expired. Please start over.” — occurring immediately after a successful passkey authentication.
- A more specific internal error: “Route Error (405 Method Not Allowed): Route ‘AUTH_CHALLENGE_SELECTION’ does not have an action, but you are trying to submit to it.”
This issue closely resembles one reported by another user in this same forum (“Authentication succeeds, but retrieval of session fails with ‘session expired’”), who had also enrolled in Advanced Account Security and encountered the exact same session-expired error immediately after successful authentication, across multiple devices. This strongly suggests the issue lies in the authentication flow itself, rather than on my end.
As a result, I’m currently locked out of my account for the full 48-hour period, which is causing real professional harm, since I rely on ChatGPT daily for my work. I would greatly appreciate a prompt review and resolution, given the impact this is having.
