Regaining access to a LinkedIn ad account can be blocked by a missing or misconfigured authenticator app entry. This is a common issue when accounts were set up under a previous device, app install, or team member — and the authenticator code was never migrated or documented.
This article covers the symptoms, likely causes, and recovery path for LinkedIn ad account login failures tied to authenticator issues.
LinkedIn ad accounts with two-factor authentication (2FA) enabled require a time-based one-time password (TOTP) from an authenticator app (e.g., Google Authenticator, Authy). If the account was originally set up on a different device or the authenticator app was reinstalled without backing up entries, the TOTP seed is lost and no valid code can be generated.
"I went in there and looked and it said that I had had an account, but then when I tried to log into it, it put me into some loop... What's your authenticator code? And I look at my authenticator, I don't have a LinkedIn code."

LinkedIn provides one-time backup codes at the time 2FA is set up. Check any secure password manager or documentation from when the account was originally configured.
LinkedIn offers an account recovery path for users locked out of 2FA:
- Go to the LinkedIn login page and click "Forgot password?" or look for a "Having trouble?" link on the 2FA prompt
- Follow the identity verification steps (email, phone, or ID verification)
- Once verified, LinkedIn may allow you to disable or reset 2FA
If self-service recovery fails, contact LinkedIn support directly. For ad accounts, LinkedIn Business Support may be able to assist with account verification and access restoration.
If the ad account is a LinkedIn Campaign Manager account, another admin on the account may be able to remove the locked user and re-invite them, bypassing the 2FA issue entirely.
