Hey @mjezegou35
Thanks for reaching out! Our support policy covers the current and previous major versions of WordPress.
With WordPress 6.9 being the latest release, we actively support 6.8 and 6.9. Since you’re on 6.6.2, that version falls outside our current support window, which is why we’re unable to guarantee compatibility or troubleshoot activation issues on that version.
We’d strongly recommend upgrading WordPress to 6.9 — the current plugin release is fully compatible and multisite network activation will work as expected.
If upgrading isn’t an option right now, you can install an older release of the Two Factor plugin as a workaround. We’d suggest version 0.14.2, which is the last release before the minimum WordPress requirement was raised to 6.8.
You can download it here:
https://github.com/WordPress/two-factor/releases/tag/0.14.2
Please note: we don’t recommend staying on an older plugin version long-term, as it won’t receive bug fixes or security updates. This should only be a temporary solution while you plan your WordPress upgrade.
Let us know if you have any other questions!
