在更改密码之前,您将能够使用
reauthenticate实现它.
let user = FIRAuth.auth()?.currentUser
let credential = FIREmailPasswordAuthProvider.credentialWithEmail(email,password: currentPassword)
user?.reauthenticateWithCredential(credential,completion: { (error) in
if error != nil{
self.displayAlertMessage("Error reauthenticating user")
}else{
//change to new password
}
})
