This article explains what causes the following error and how to troubleshoot it:
Your device's TPM is locked, and Okta Verify cannot be used for authentication.
- Authentication
- Okta Verify
- Trusted Platform Module (TPM) lockout
According to the Manage TPM lockout article published by Microsoft, the TPM locks itself to prevent tampering or malicious attacks. TPM lockout often lasts for a variable amount of time or until the computer is turned off.
TPM lockout may be triggered when a user enters the incorrect passcodes in Okta Verify several times in a short period of time, but it may also be triggered by other applications or the Windows Operating System.
The TPM lockout can be reset by rebooting the computer or using the TPM MMC. For details, please follow the Reset the TPM lockout by using the TPM MMC section in the article above.
