Using ewelink on 2 phones

I have 2 phones could I use the same account ewelink?

Hi. Use the same account on 2 phones will make you successfully log in to on one phone and log out on the previous phone. If you want to save the trouble of entering a password every time you log in on a different phone, it is recommended that you register another account and then share the device for a better experience.

We are considering multi-login for different devices by one account, need time to work out a plan for this.
