That means that the 1st 30 seconds since midnight Jan 1st,ġ970 UTC (00:00:00 – 00:00:29) the timestamp – equivalent of the counter in HOTP – wasĮqual to 0. The timestamp that TOTP is using is simply the UNIX timestampĭivided by 30 and rounded down. Seconds, and, by doing that, the user would have up to 30 seconds to type in the code. Having the timestamp increment by 1 every half a minute would make the code valid for 30 1 second to enter the code would not be enough, thus we have to make the timestamp That timestamp, but – since the timestamp changes every second – the code would change every We could design the algorithm to simply calculate the HMAC-SHA-1 directly from the key and It’s a large unsigned integer that is being incremented by 1 every second. UNIX timestamp is nothing more than a number of seconds that have elapsed since the midnight Then is generating the code off of the resulting hash the same way as in HOTP. It’s calculating HMAC-SHA-1 using the key and a BigĮndian representation of a counter, but the counter is based off of UNIX timestamp. One way to avoid the problems with lack of feedback between server and the app would be to shiftįrom using a counter that is increasing with every authentication attempt to a counter based Base32 algorithm – used to store non-printable secret in a URI (effectively stored.QR Codes used to easily transfer secrets from the server to the Authenticator app.On things common to both, HMAC-Based One- Time Password algorithm: You can scan a QR code on the old device, which imports everything to the new one.Part 3 is the last part in this short cycle. Google Authenticator also has a neat option to transfer your accounts between phones. Google Authenticator backs up to your Google account. iOS users must also be signed in to an iCloud account, since that is where the backup is actually stored. Microsoft Authenticator backs up your account credentials and related app settings to its cloud, which requires a Microsoft account. Microsoft and Google Authenticator apps let you back up your 2FA accounts in the cloud and restore them when needed, which is handy when changing devices. However, if you're using Google Authenticator, you must manually copy that 6-digit code and then paste it into the code field-no autofill. Microsoft Authenticator can automatically fill in those authentication codes in Microsoft apps and third-party apps that support it. But logging in is not needed for third parties like Facebook. Google Authenticator also requires logging into your Google account to enable 2FA for Google services like Gmail, backups, and syncing. Once your passwords are in Microsoft Authenticator, you can back them up to a CSV file if you need to transfer them elsewhere. Even better, while it can help you generate new passwords, it can also pull in passwords already saved in Google Chrome or other great password managers such as 1Password, Dashlane, NordPass, and more. It has a password manager that securely stashes away your login credentials for various apps and websites. Additional Featuresīeyond just churning out login codes, Microsoft Authenticator offers some other handy capabilities. Google Authenticator, on the other hand, sticks exclusively to the 30-second time-based or counter-based codes. And if your device supports it, you can use biometrics like fingerprints or face recognition to autofill generated codes. You've got your standard time-based codes that change every 30 seconds, but you can also use push notifications to approve sign-in requests, which pops up a notification right on your phone to tap. Microsoft Authenticator offers you different ways to authenticate. We will delve into the nitty-gritty details of each app, but before that, here is a comparison table of key features between Microsoft Authenticator ( Android | iOS) and Google Authenticator ( Android | iOS). Microsoft Authenticator vs Google Authenticator: A Quick Comparison They serve the same core purpose, but some key differences are worth considering before deciding which to use. Microsoft and Google offer free authenticator apps that generate time-based one-time passwords for two-factor authentication (2FA) logins. Microsoft Authenticator requires a Microsoft account sign-in and offers autofill capabilities, while Google Authenticator requires a Google account sign-in and does not have autofill capabilities.Microsoft Authenticator provides additional features like password management, payment card storage, address management, and Verified IDs, while Google Authenticator focuses solely on generating authentication codes.Microsoft Authenticator offers more authentication methods, including time-based codes, push notifications, and biometrics, while Google Authenticator only offers time-based or counter-based codes.
