Can I have more than one Clef account on a single device?

Currently, Clef accounts are limited to one account per device. 

Adding multiple account support (e.g., a personal and business Clef account) on one device, and adding account syncing (i.e., the ability to sync a Clef account across multiple devices such as using your Clef account both on your personal phone and your work phone) are on the product development roadmap.
