ICQ 8

To add another account to ICQ, enter the ICQ number, email address, or phone number linked to the ICQ account, along with the password used to sign in.

To verify that what you entered is correct, click "Test account". You can also register a new account by clicking "Sign up for ICQ".

If you want this account to automatically connect at the same time as the primary account, check the appropriate field.

If this option is not enabled, then the account will only connect manually. To do this, you will need to right-click on the account's current status and select the desired status. If you check "Same as the primary account", then your ICQ status will be synchronized with ICQ's primary account.

When you are done making changes, click "ОК".
