Oktopost allows you to sign in using the email and password you created for the account or using your accounts on Facebook, LinkedIn, and Twitter.
To use either one of the social networks for authentication, you will first have to be logged to Oktopost and connect your account to the relevant network. Once a connection has been established, future logins can be done using your social network credentials.
To connect your account head over to Social Login under My Settings and click on Connect next to the network you want to use for authentication.
You will then be redirected to the social network. Make sure you click Approve on the permissions screen, otherwise you will not be able to connect using your social account.
To remove your social login, click Disconnect under the relevant network.
