Nginx Proxy Manager 2.13.6 adds TOTP-based two-factor authentication (2FA), along with certificate key-type selection and several logging and DNS-related changes. However, it is no longer in the project’s stated supported release line: the security policy says only the latest stable release receives security updates and listed 2.16.x as supported when checked. Before deploying or staying on 2.13.6, check the latest releases and the project’s security policy.
What two-factor authentication does 2.13.6 add?
The release notes describe the feature as “Add TOTP-based two-factor authentication.” TOTP, or time-based one-time password, is the kind of rotating code commonly used with authenticator apps. The release announcement establishes that Nginx Proxy Manager added TOTP-based 2FA; it does not specify supported authenticator apps or physical devices, enrollment steps, or how account recovery works. See the official release listing for the project’s wording.
That distinction matters: the notes do not claim that this release added passkeys, hardware-key login, or every form of multi-factor authentication. They also do not provide enough detail to give reliable instructions for enabling TOTP or recovering access if a second factor is lost.

Is version 2.13.6 still supported?
No—not according to the support information available for this release snapshot. The project security policy states, “Only the latest stable release receives security updates.” It identified 2.16.x as supported and older versions as not actively maintained; the releases page also lists versions newer than 2.13.6. Because release status changes, check the live security policy and release list before making a deployment decision.

How is 2.13.6 distributed?
Nginx Proxy Manager describes itself as a Docker container for managing Nginx proxy hosts. The 2.13.6 release listing gives the image tag jc21/nginx-proxy-manager:2.13.6. That tag identifies the versioned image; it does not establish that the release is currently supported or provide a safe upgrade procedure. Check the project’s version-specific documentation before changing an existing deployment, since compatibility and upgrade steps are not established by the release notes.
