You can change your avatar at will. I don’t quite understand what you mean. Do you mean to say, can two mobile phones log in to DingTalk at the same time?

1. First of all, you can log in to the computer and mobile phone at the same time, but as we all know, the computer is the client and cannot check in.

2. In addition, the iPad can be logged in with the mobile phone at the same time. If you put the iPad in the office and hold the mobile phone by yourself, you can let your colleagues use the iPad to check in for you in the office.

3. However, two mobile phones cannot log in to the account at the same time, so if you want to be outside and have someone check in for you, you can only use an iPad and a mobile phone. I hope this can help you.

4. Finally, I wish the host all his wishes come true.
