Yes! You and your partner can both be logged into a single account on multiple devices. The second parent will enter the phone number associated with the main account. The phone number entered will receive the 6 digit verification code texted to the phone number associated with the active account. This code is only valid for 5 minutes so you will both need to be ready when your partner is logging in from their device.
This will allow you both to be able to share one account and create requests, message with sitters and pay the sitter at the end of the sit. Please contact email@example.com with any further questions.
