We can receive verification codes at the alternate email
If you have exhausted all other methods, but can complete one verification step for your account (e.g. code via email), but can't access any of the other verification methods, and have repeatedly failed the Account Recovery process, or can't use Account Recovery because your account has Two-step Verification (2FA, MFA), then you can try to request that all the verification methods be replaced.
This will put your account in a 30 day "Pending Request" state. You will have limited access to the account during this period or no access at all if the account has Two-step Verification enabled.
