Why Are My n8n API Keys Expiring Unexpectedly After the Update?

Hey there,
I was using an active n8n API key per environment without any issues, and they were being used daily. However, starting Feb 19, all my keys expired at once. I recall a recent update in the release notes mentioning a new API key feature (available only in Enterprise for multiple keys with expiry dates).
My assumption is that during migration, keys that were supposed to never expire might now default to a one-week lifetime if no expiration is explicitly set. Notably, my production environment running version 1.75.1 isn’t affected, which suggests the change occurred in versions 1.78.1 and 1.80.0.
The error message I get is:
Authorization failed - please check your credentials
jwt malformed
n8n Setup Information:
- n8n version: 1.78.1 and 1.80.0
- Database (default: SQLite): Postgres
- n8n EXECUTIONS_PROCESS setting (default: own, main): main
- Running n8n via: Docker
- Operating system: Ubuntu 20.04 LTS
Has anyone experienced this issue or have advice on how to configure the new API key behavior—either by explicitly setting keys to never expire or adjusting the default expiry settings?

It sounds like you’re experiencing issues with the new API key behavior that was introduced in our recent Enterprise updates. With the changes, API keys are now implemented as JWT tokens and can have an expiration date attached. If you don’t explicitly set an expiration when creating a key, the system may use a default lifetime (for example, around one week). This would explain why keys that used to “never expire” before the migration are now suddenly considered expired (leading to the “jwt malformed” error).
In your case, because your production running version 1.75.1 isn’t affected, the change appears to come in with the upgrade to versions 1.78.1/1.80.0. To resolve the issue you have a couple of options:
• Re-create your API keys using the new API key (JWT) configuration and explicitly set them to never expire—or at least set an expiration date far in the future if that suits your security needs.
• Alternatively, if the change wasn’t expected or desired, you might consider remaining on your stable production version until you’re ready to adopt the new API key behavior.
For more details you might want to review the updated release notes and our documentation on API key management, as they now outline how to generate multiple (Enterprise-only) keys with custom expiration dates. This will help ensure that after migration your keys continue working as you intend.
Let me know if you need further guidance on generating new API keys or if you have any more questions regarding this behavior!
