We regret to inform you that due to low demand, we have made the difficult decision to discontinue development of our WordPress plugin. We appreciate the trust you’ve placed in us and are grateful for your continued support.
Please note that while our servers will continue to operate, supporting the SecSign App, we will no longer maintain or update the WordPress plugin. You can still use the existing version, but we won’t be releasing any further updates.
As a precaution, we recommend exploring alternative solutions to ensure compatibility with future WordPress updates, as the plugin may cease to function properly.
Unfortunately, due to the unique nature of our plugin and its integration with the SecSign App, we are unable to recommend an alternative solution that can provide the same level of functionality and security.
We apologize for any inconvenience this may cause and appreciate your understanding in this matter.
Once again, thank you for your loyalty and understanding.
Best regards,
The SecSign Team

The SecSign ID two-factor authentication WordPress Plugin will be discontinued.
