Connections established with any of the external accounts uses a protocol called Oauth, which enforces heavy security standards to protect the user from any harm. This procedure strictly prohibits Wefitter to see or store the username and password to these accounts. Access of the types of data and the usage has to be authorized by the user before Wefitter can use it. Along with regular token expirations, users are able to disestablish the connection by resetting the token through settings in the respective social network accounts, always giving the users the ability to change their mind.
