Maximum result with minimum effort, in short, to simply allow Authenticator to continue its service without frills that can annoy or news that can destabilize the user experience on a tool that is as useful as it is essential.
How it works
Google Authenticator uses HOTP and TOTP algorithms to generate tokens useful for confirming an identity. The user who uses the service can leverage his smartphone to confirm his identity on sites, apps and online services and no scam can be carried out to the detriment of the identity of the same if you do not have direct access to the smartphone. The "two-step verification" can thus be carried out through open standards and with tokens lasting 60 seconds, upon expiry of which a new one is generated.
