func (*Auth) AssignMedia

func (a *Auth) AssignMedia(userid, media string) error

func (*Auth) AssignTOTP

func (a *Auth) AssignTOTP(userid, url string) error

assign a TOTP to a user

The TOTP secret is not stored encrypted. May change this later but would need a way to protect passwords used to encrypt secrets.

Entire otpauth URL is stored to support future use of different parameters.

func (*Auth) AssignedMedia

func (a *Auth) AssignedMedia() []string

func (*Auth) AuthorizeCode

func (a *Auth) AuthorizeCode(value, token string) error

This assumes token is valid

func (*Auth) ChangePass

func (a *Auth) ChangePass(userid, newpass string) error

ChangePass changes the password associated with the provided userid. User Check prior to this if you'd like to verify the current password.

TODO this should trigger a TOTP change as well.

func (*Auth) CheckAccessToken

func (a *Auth) CheckAccessToken(signedToken string) error

func (*Auth) CheckAccessTokenUser

func (a *Auth) CheckAccessTokenUser(signedToken string) (User, error)
