Recovery codes are the spare key for two-factor authentication, and losing them at the same time as the second factor leaves only the account recovery path. It is slower and stricter by design, because it is the last line of defense against someone else claiming the account.
If recovery is rejected, submit again with more accurate history, since the review compares the answers against what the service has on file. Microsoft allows up to two recovery forms a day. For a work or school account, the organization's IT administrator is the one who can reset the sign-in method. If no proof is accepted, the account may not be recoverable, which is exactly why the codes matter, so treat the fresh set as carefully as a password once access is restored.
Store backup codes in a password manager plus a printed copy kept somewhere safe, separate from the phone they protect. Never store them only on the phone, since losing the phone loses the codes too. Keep the recovery email address and phone number on every important account current, and test one backup code after setup, so a bad copy is found while access still works.
Can support turn off two-factor authentication for me? No. Support agents cannot bypass or disable two-factor authentication on request. The service's account recovery process is the path back in, and it verifies identity before restoring access.
Should I share a recovery code with support to prove the account is mine? No. Never share a password, verification code, or recovery code with anyone, including anyone claiming to be support. A real recovery process never asks for a code.
How should I store backup codes? Store them in a password manager plus a printed copy kept somewhere safe, separate from the phone they protect. Never store them only on the phone, since losing the phone loses the codes too.
