At this time, each user's login credentials (email address and/or phone number) must be unique across all our customers: as a result, a user would not be able to have multiple profiles with the same information.
Some users who are part of multiple Blink organizations have their email address in one and their phone number in the other in order to maintain both accounts. To switch between accounts on mobile, the user would need to log out/in to each account as required. For desktop users, you can leverage multiple browsers and/or private browsing windows to accommodate this.
