How to Add Authenticator Again Osrs
2-factor authentication has get an essential security precaution for many people, but it can also be a source of feet. When you change or upgrade phones, Google Authenticator doesn't drift codes automatically—you need to do that manually.
Thankfully, information technology's not difficult to move Google Authenticator codes from 1 phone to another, although, admittedly, information technology can be somewhat cumbersome and time-consuming. Google intended this, more or less, by design. It shouldn't be too easy to retrieve hallmark codes from anywhere except the device you're using for your two-factor authentication, or the whole value of 2FA would be moot.
Even so, here'southward what you lot need to know to go Google Authenticator (and all of your authentication codes) from an old phone to a new one. Whether you're jumping platforms or staying inside your iOS or Android universes, the process is the same.
Motility Google Authenticator to a New Phone
First of all, don't practice anything to the re-create of Google Authenticator on your one-time phone. Go out it be for now, or else you might get caught without a way to enter 2FA codes earlier the new phone is gear up. Start by installing Google Authenticator on your new device—either Google Authenticator for iPhone or Google Authenticator for Android.
Next, you'll need your figurer. Open Google's two-Step Verification page in a browser and log into your Google business relationship when it asks y'all. In the "Authenticator app" department of the page, click "Modify Phone."
Choose the kind of phone you are migrating to and click "Next."
You should now see the "Prepare up Authenticator" screen, complete with barcode. Open Google Authenticator on the new telephone and follow the prompts to scan the barcode. Tap "Setup," and and then "Scan a Barcode."
After the browse, you'll want to enter the former code to verify it's working.
Transfer Your Google Authenticator Codes for Other Sites
Congrats! You've now moved Google'south hallmark lawmaking to the new phone, but that's all; the simply service you've set up up is Google. You probably nevertheless have a slew of other apps and services connected to Google Authenticator—perchance Dashlane, Slack, Dropbox, Reddit, or others. You'll need to migrate each of these, one at a time. This is the time-consuming role we alluded to earlier.
But the overall process is straightforward, even if you need to hunt effectually a chip for the settings. Selection a site or service that's listed in your old copy of Google Authenticator (on the erstwhile phone) and log into its website or open the app. Find that site'southward 2FA setting. It's probably in the account, password, or security section of the website, although, if the service has a mobile or desktop app, it might exist there instead. Case in point: The 2FA settings for Dashlane are found in the desktop app, not the website, while Reddit puts the 2FA controls on the site in the "User Settings" menu, on the "Privacy & Security" tab.
Once you notice the right controls, disable 2FA for this site. Yous'll probably need to enter the password for the site, or possibly the authentication code, which is why you'll desire to have the old phone and its re-create of Google Authenticator handy.
Finally, re-enable 2FA, this time scanning the QR lawmaking with Google Authenticator on the new phone. Repeat that process for each site or service listed in your old copy of Google Authenticator.
Enable 2FA on More One Device at a Time
In a perfect earth, 2FA allows yous to ostend your credentials using a mobile phone or some other device that you lot carry with you lot all the fourth dimension, which but you have access to. This makes it very hard for hackers to spoof the arrangement, considering (dissimilar getting codes via SMS, which is non especially secure) there'due south no easy way for bad guys to become their easily on a second-cistron authorization delivered via a local app that exists but in your pocket.
Here's what's happening behind the scenes. When you add a new site or service to Google Authenticator, information technology uses a secret key to generate a QR code. That, in turn, informs your Google Authenticator app how to generate an unlimited number of fourth dimension-based, one-time passwords. Once you scan the QR code and close the browser window, that particular QR code tin't be regenerated, and the secret central is stored locally on your phone.
If Google Authenticator were able to sync across multiple devices, then the cloak-and-dagger fundamental or its resulting authentication codes would take to live in the cloud somewhere, rendering information technology vulnerable to hacking. That'south why Google doesn't allow you sync your codes across devices. However, there are 2 ways to maintain authentication codes on multiple devices at once.
First, when you add a site or service to Google Authenticator, you lot can browse the QR code onto multiple devices at once. The website that generates the QR code doesn't know (or care) that yous've scanned it. You tin can scan it into any number of additional mobile devices, and every copy of Google Authenticator you scan from the aforementioned barcode will generate the same half-dozen-digit lawmaking.
We don't recommend doing information technology this way, though. Commencement of all, yous're proliferating your hallmark codes to multiple devices that tin exist lost or stolen. But, more chiefly, since they're not really in sync, you run the risk of getting the diverse devices out of sync with each other. If you demand to turn off 2FA for a particular service, for instance, and then only re-enable information technology on one device, yous may no longer know which device has the nigh electric current and right authentication codes. Information technology's a disaster waiting to happen.
Use Authy to Make This Easier
Information technology is possible to sync your authentication codes across devices—you just can't practice it with Google Authenticator. If you want the flexibility of having all of your 2FA codes on multiple devices, we recommend Authy. It works with all the sites and services that employ Google Authenticator, and information technology encrypts the codes with a password you lot provide and stores them in the cloud. This makes multiple devices and migration much easier, and the encrypted deject-based sync offers a balance of security and convenience.
With Authy, you don't need to set up 2-factor authentication for all your devices every time yous move to a new phone. We recommend making the switch from Google Authenticator to Authy to make the new-phone migration process easier in the future.
