++Adding to the topic and updating this old tread,

Hi @Meenakshi Negi  and @aleksanderl99843310 ,

I believe that @aleksanderl99843310  is using Acrobat Sign enterprise licensing plan or Adobe Acrobat Sign for Teams subscription because phone and password  authentication seems to be available with those plans only at this time:

• https://helpx.adobe.com/sign/config/send-settings/auth-methods/phone-auth.html

• https://helpx.adobe.com/sign/using/get-started-guide.html

The individual plan that is shipped with Adobe Acrobat only allows to share  and authenticate with email and password.

Based on what I'm reading, currenrly only US numbers are supported through  different carriers, in which case @aleksanderl99843310 you may need to contact Acrobat Sign support directly at:

Here is a helpful link:

Hope this helps.

In addition, if you suspect this could be a bug or a feature that is missing in your plan, you may use the channels (listed below) to route your requests directly with Adobe:
