You can easily login with your Facebook profile or your Google account.
After clicking the Login button with the Facebook/Google option, a pop-up will appear asking you to agree that Grindr wants to log in with your Facebook/Google account.
The Facebook/Google App will open for login authorization.
Note: If Facebook/Google is not installed on your device, it will direct you to the browser for login authorization.
After the authorization is completed, you will return to the Grindr App and your Profile information will be displayed and you will be able to modify this information.
Note: When your Facebook/Google account already exists in the Grindr's account system, it will log you into your existing profile.
