This happens because your browser thinks these fields are username instead of email. If you use another browser to check it, you will probably see that the fields stay cleared.

If you go to edit profile and you will see only email, the reconfirm email disappear but when I go to back end, I can see like my attachment...

If you we fix this error, I will check with Safari and Firefox about email change to username in there..

Hi Savry,
Actually the reconfirm email field only display in registration forms or if the system detected that the user is changing their email address. This is why you see the reconfirm field when there is a change in your email address.

Thanks Sabih for the response.
Savry, can you tell us which browser did you use when the browser saved username was injected in the email field? By right the browser should not be injected values when the field has autocomplete set to 'off'(http://take.ms/yjZU5).

I always use Safari.

Hey Savry,
It looks like this is an issue for the browser as Safari is not respecting the autocomplete="off" in HTML markup.

Perhaps you can try other browsers. The email field autofill should be working in other browsers.

If I go to edit profile, I note the email and confirm change it by itself..
The email change to become username so I need to retype the email to match with confirm again....
thank you

Hey Savry,
Perhaps you can remove the saved password from Safari's saved passwords list(http://take.ms/uhVLj) since the autocomplete does not work in Safari.
After you do this, can you try heading to the profile edit page again and see if the issue persist? Thanks.

I removed but it still the same.

Could you test it with Safari and you will see about password and the email field replace by username in thier field.

Thank you.

Hey Savry,
I have tested this on my colleague's Safari browser and it works. Once I deleted the saved password for that user account and re-logged in, the username no longer appears in the email field.
Try clearing your browser cache too.

Hey Savry,
Glad to know that your issue is resolved.
Regards.
