Members are required to verify their identity when they log in as an existing member. This can occur if they log out from the app, if they are registered as members from the business-side app or the Como Hub, or if they switch devices.
There are three login validation methods businesses can use: SMS, email and custom.

SMS Login Validation
After the member taps to log in as an existing member, they enter their phone number and receive an SMS with the validation code. They then enter this validation code to log in.
To set up the SMS validation method:
- Add the phone number field to the registration form as a required field.
- From Operation > Settings > App Settings:
- Add phone number as a unique field.
- Select SMS for App Login Validation Type (Existing Members) and click Save.
- From Operation > Settings > External Services:
- Select an SMS Service Provider, enter the SMS Sender name and click Save.
NOTE: If you'd like to use Como's account, check Use default credentials. If you'd like to use your own account, enter your account username and password.
Email Login Validation
After the member taps to log in as an existing member, they enter their email address and receive an email with the validation code. They then enter this validation code to log in. Businesses may prefer this method over SMS validation since it’s cheaper and members may prefer to give their email instead of phone number.
To set up the email validation method:
- Add the email field to the registration form as a required field.
- From Operation > Settings > App Settings:
- Add email as a unique field.
- Select Email for App Login Validation Type (Existing Members).
- For Email Sender Name (not email address), enter the “from” name that will appear on the validation email.
- Click Save.
Custom Login Validation
The custom verification method allows members to verify their identity using two fields: one unique field (member ID, government ID, etc.) and another field (name, favorite branch, etc.).
NOTE: When members enter the custom values in the app, they must enter them exactly the same way as they did in the registration form (since it's case sensitive).
To set up the custom validation method:
- Add the fields you plan on using for validation to the registration form as required fields.
- From Operation > Settings > App Settings:
- Add the field you'd like to use as the unique field.
- Select Custom for the Login Validation Type (Existing Members).
- Select a unique field and an extra field for validation.
- Click Save.
