Switch between different Customer Portal on Android and IOS APPS

Switch between different Customer Portal on Android and IOS APPS



Hi everyone,
I have several customers who should use more than one customer portal that I have made available to them.
Many of these customers use customer portals on their mobile devices (ios and android) and they must disconnect/reconnect everytime to switch between different customer portals. It would be fantastic to have the ability to configure more than one access to the mobile app getting the ability to switch from one portal to another simply with a tap or swipe (like most applications...).
Maybe the solution already exists ???
Thanks for the answer someone want to give me.
