It is possible to restrict users to login with a certain email domain. This can be configured through the Domain restriction section in the Sign in Settings tab.
- Go to Sign In Settings tab and enter the domain name against Allowed Domains which should be allowed for login.
- Save configurations.
Allowed Domain is miniorange.com then the users with emails ending with miniorange.com will only able to log in. For example, a user with abc@miniorange.com can log in but a user with xyz@example.com will not be able to log in.
