Hi,
1) Yes, this is possible, you can choose this option in Easy Profile configuration (Components->Easy Profile->Options), see "Login Type" parameter

2) Yes, you can choose a field to be available only on backend. If you want to allow to the admin to edit this field from frontend then you can enable the parameter called "Admins can show not editable fields in frontend" in Easy Profile configuration (Components->Easy Profile->Options)

3) For each field you can set to be available in Profile page (also if the field is not available in Edit Profile page)

Hi @resif, you have replied to this topic, but you have shared your credentials in clear. Normally to send access details you should use the form below the reply (in the tab called "Site Details". Now I have hidden your access, but it was public, so you should change the password in your site.

@resif you should thanks @prffrost to this report, you have published on our forum your details in clear in a topic not referred to you or some your question.

Anyway we cannot allow this language on our forum, otherwise we will ban your account

Hi @resif, you have posted these details in a wrong post [#27984], I have sent you our notification email received at 16 February.

This confirm that we have not a security issue in our forum and this is a human error.

I’m really sorry about this, normally we check this and automatically we delete public details, but in many cases details are referred to developing sites.

"Resif you probably wrote wrong place when i ask your site details..."

I understand, we try our best. we have read the notification to solve your issue asap and conversation gone ahead with many other replies. We (and you) didn't notice it
