Changing your phone number is simple. To do so, please follow these steps.
1. In your Bake mobile app, please go to your settings by clicking the profile icon on the top left and then tap the Your account item.
2. There you will be able to check your profile information, including a section showing your current linked phone number. You can change that number by tapping there.
3. After that you will be asked to authenticate yourself by entering a verification code (2) that will be sent to your registered Email address (Important: In order to trigger that email, please tap the Send button (1) on the right), as well as inputting your 2FA code below (3). If you have not set up any 2FA yet, you need to do that first, before you can change your phone number (Please see how to do this here: How do I secure my account with 2FA?). After you put in the Email verification code and the 2-factor authentication code, tap Verify (4).
4. After successfully authenticating yourself, you will be given the option to input a new phone number. Please follow the remaining instructions on the screen, and that's it! You have now successfully changed your phone number.
