When a customer has trouble logging in, a few basics will help you sort it out quickly.
Every customer has one login method
Each GrownBy account uses a single login method: a phone number, or an email and password, or an Apple or Google account. Whichever method the customer set up first is the one tied to their account.
A customer cannot log in a different way to reach the same account. For example, if their account was created with a phone number, signing in with their email will not open that account. It will either fail or start a brand-new, empty account. They have to use the method their account was set up with.
How phone number login works
Phone login has no password. When the customer enters their phone number, GrownBy sends a one-time code by text message. They type that code in to finish logging in. Some phones detect the code automatically and fill it in or offer it above the keyboard.
Codes are delivered over the cell network, so they can be slow to arrive (or not arrive at all) when the customer has weak signal or wifi. If a customer isn't getting their code, the first thing to check is whether they're somewhere with good cell service.
When a customer keeps having trouble
If a customer has ongoing problems receiving text codes, it's often easier to switch them to email and password login instead. The GrownBy team can change a customer's login method, for example from phone to email.
