Hello everyone, I’ve been using Openemr for 6 months but when I installed it I missed the MFA security part. Hope someone can show me how to reinstall this feature without reinstalling everything? Since I’ve adapted the changes to how the base structure works, it’s a pain to set it all up again from scratch. Thanks everyone. ---

You should be able to do it from the user menu in the upper right hand corner… ![MFA](https://discourse-uploads-openemr.s3.dualstack.us-east-1.amazonaws.com/original/3X/7/b/7b38f99b72c648c95cd3f3d3c88b3e97f130e0ae.png) ---

Dear Mr. @DrBassmanOD Thank you for supporting me, but I had done that way for TOTP and had pass by the password requirement then the QR code not show up at the TOTP Registrasion page. ![pif](https://discourse-uploads-openemr.s3.dualstack.us-east-1.amazonaws.com/original/3X/d/4/d42941b05e12bb4d26ba09a006ef33b3de94c0cf.png) ---

There was a bug in that screen where you MUST click the button with your mouse after typing your password. If you hit the enter button, the QR code was not displayed, but if you clicked it with the mouse it was. It is fixed in version 7.0.2 if you are running an older version, the bug is still there. Try that. ---
