User Profile: General Info

A user profile is their personal account, which can be linked to an account on a corporate server.

What Types of Profiles Are There?

Profile Type	Description	Servers
Public Profile	A registered personal account not linked to an account on a corporate server.	RTS
Corporate Profile	A registered personal account linked to an account on a corporate server.	Lite CTS eCTS
Guest Profile	A temporary profile without registration for joining a chat or conference via an invitation link.	RTS or CTS eCTS

Is It Possible to Use Several Different Profiles Simultaneously in the App?

This feature is not available. To switch to another profile, you need to log out of the session in the previous profile.

Can I Merge Several Profiles Into One?

This capability is not provided by the app architecture.

Profile Identification by HUID

The unique identifier of a profile is not a mobile phone number, login, or email, but the HUID (Human Unique Identifier) of the personal account. The HUID consists of 32 alphanumeric characters separated by hyphens.

Can a User HUID Change?

The HUID of a profile does not change throughout the account's lifetime; a new account = a new HUID.

However, the HUID of a corporate account, which is displayed in the corporate server (

) admin panel, is temporary until the user's first login (see below).

It is the HUID of the personal account that identifies all user data stored on the servers. The HUID is also associated with personal encryption keys. When you change the linked phone number in your profile, the HUID remains unchanged.

What Happens When Connecting to a Corporate Server?

When is a New HUID Generated?

A new personal account HUID is created only when a new personal account is created in the following cases:

• registering a new account;
• the old account was deleted, and the user registers with the same phone number for a new account.

How to Check My HUID?

Your HUID can be viewed by your organization's system administrator or eXpress support team, and it is also in the profile link.

Encryption Keys

When a personal account is created, encryption keys are generated to protect user data. The private part of the encryption keys can be secured by the personal password for additional data security.
