Corporate Email

Authentication scheme using a corporate email address. Login without a phone number. Requires an existing corporate account and configured or simplified authentication (suggests).

Why Is This Button Missing in the Aurora App?

⚠️ Not yet supported in the Aurora app.

I Previously Used a Phone Number. Can I Log in via Email Now?

⚠️ If you previously logged in with a phone number, it is highly recommended to use the Phone and Credentials button or connect to the corporate server in the profile settings (eXpress). Otherwise, linking a new number may result in message history loss (another account is created).

What Happens After Entering Corporate Email?

Then, depending on server settings, you may need to:

• select a server (check with your organization's support team),
• enter credentials,
• confirm login with a code from the email,
• or manually enter the server address.

Explanation for Administrators

At this step,

RTS

or

ETS

searches for domains associated with the email (if simplified authentication is configured).

• If the server is found and the user exists — proceed to the next step.
• If not configured — "Corporate email not found" error.

What Does the “Leave the Server” Button Do?

When logging in again, you can log out from the corporate server using the Leave the server button (request for logout). The same device will be required to log in again.

Why Was SMS Verification Still Required?

This means the system detected a mobile phone number linked to the profile.

Phone number verification via SMS code is not performed when:

• You, as a public
  RTS
  server user, connect to a corporate
  CTS
  server via Settings > Profile in eXpress app.
• SMS verification upon login by email or server address is disabled by your corporate server administrator for the internal corporate network, and you are connecting from within it.
