Key Features of Your TSP Digital Portal

Resolving Access Challenges for Your TSP Account

⚠️ Forgot Username or Password

Cause: Inability to recall your established username or password for the My Account portal.

Solution: If you forget your username or password, use the 'Forgot Username' or 'Forgot Password' links available on the tsp.gov/login page. Follow the prompts to verify your identity and securely reset or retrieve your credentials. For password resets, you will receive a verification code.

⚠️ Account Locked or Unable to Login

Cause: Multiple incorrect login attempts, issues with multi-factor authentication, or changes to your validated phone number.

Solution: We know being locked out is stressful. First, try the 'Forgot Password' or 'Forgot Username' options. If issues persist, particularly with multi-factor authentication or a changed phone number, you may need to call the ThriftLine at 1-877-968-3778. Have your ThriftLine PIN ready to authenticate your identity over the phone for assistance.

⚠️ Issues with One-Time Passcode (MFA)

Cause: One-time passcode not received via text/call, or code not accepted.

Solution: Ensure your validated phone number is correct and able to receive texts or calls. If you aren't receiving codes, check your phone's signal or spam filters. If you have both text and call options, try the alternative delivery method. If the code expires before you can enter it, request a new one. If you've changed your phone number, you may need to update it by calling the ThriftLine.
