Can I have multiple accounts on the same device?

No. It has to do with the fact that our platform is built on something we call trusted devices. A trusted device can only be linked to one phone number and one person, in other words, one account per device. The same also applies to browsers in computers. So if you are a household that shares a computer, only one person per browser on the same computer can have it as a trusted device. Does a person e.g. have chosen Chrome as its trusted device, another person may have Firefox or Safari as their trusted device on the computer.
