Secure authentication of third-party applications and/or websites may be facilitated using a biometric-enabled transitory password authentication device. Exemplary implementations may replace a login requirement with a simple and secure swipe-to-authenticate mechanism in order to gain access to a third-party application and/or website. According to some implementations, a user may have a user computing platform linked to a physically separate authentication device. The user may access the third-party application and/or website via the user computing platform. The user computing platform may detect a login requirement associated with the third-party application and/or website. The user computing platform may prompt the user to swipe-to-authenticate. By using the swipe-to-authenticate mechanism, the user may gain access to the third-party application and/or website.
