How to Fix: Thunderbird error when importing gpg key

Learn how to fix: Thunderbird error when importing gpg key.

Quick Answer: Try resetting the master password and then reimporting the PGP key.

Thunderbird error when importing GPG key occurs when you try to import a GPG key without entering your master password. This issue affects users who have forgotten their master password and are trying to reimport a previously working secret GPG key.

This error can be frustrating as it prevents you from using the imported GPG key for encryption or decryption purposes. The following steps will guide you through the process of resolving this issue.

⚠️ Common Causes

  • Another possible cause could be a misconfiguration in the OpenPGP Key Manager or an issue with the way the GPG key is being imported.
