![]() ![]() The salt is generated using a secure random value.We salt the password before starting the 1000 rounds.This number will increase as the low range Android phone’s processor power increases. It’s a one-way function – it cannot be decrypted back and is one of the strongest hash functions available. We use a secure hash algorithm that is is one of the strongest hash functions available.The details of how this is done are quite important: PBKDF2 is a key stretching algorithm used to hash passwords in such a way that brute-force attacks are less effective. Your password is then salted and run through a key derivation function called PBKDF2, which stands for Password-Based Key Derivation Function 2.Passwords must be 6 characters long, although we recommend that you aim for at least 8 characters. (Apologies to users if this part of the post gets a bit technical, but developers will get it.) How the Authy key backups work: To make backups compatible across devices, all Authy iOS, Android, and desktop apps use the same method for encryption/decryption. The account is encrypted/decrypted inside your phone, so neither Authy or anyone affiliated with Authy have access to your accounts. For your convenience, Authy can store an encrypted copy of your Authenticator accounts in the cloud. Let’s set the record straight on how we handle encryption. If you don’t need the convenience of backups, no problem - simply keep backups disabled. You are not required to sync your keys to Authy in order to use your phone as a second factor. If you do not enable backups, your accounts will only be stored inside your phone (just like most other 2FA apps). With that said, let’s look at how this feature works. Forget it, and you lose the only way to decrypt your 2FA tokens. I also want to make it really clear that the password used for encrypting your 2FA tokens is NOT stored anywhere in our cloud service. We occasionally get questions about this particular feature from both users and developers, so this post will explain how the backup feature works in order to assuage any security or privacy concerns. That prompted a lot of users to switch to Authy in order to take advantage of our backup feature. Outside of work, Manuel enjoys a good film or TV show, loves to travel, and you will find him roaming one of Berlin's many museums, cafés, cinemas, and restaurants occasionally.A few years ago Google Authenticator released an update for their iPhone App that wiped users 2FA tokens when installed. This helps him gain perspective on the mobile industry at large and gives him multiple points of reference in his coverage. Since then, he has mostly been faithful to the Google phone lineup, though these days, he is also carrying an iPhone in addition to his Pixel phone. After running into connectivity problems with the HTC One S, he quickly switched to a Nexus 4, which he considers his true first Android phone. Manuel's first steps into the Android world were plagued by issues. He isn't shy to dig into technical backgrounds and the nitty-gritty developer details, either. He lives in Berlin, Germany.īefore joining Android Police, Manuel studied Media and Culture studies in Düsseldorf, finishing his university career with a master's thesis that offers a smooth transition to his job today, titled "The Aesthetics of Tech YouTube Channels: Production of Proximity and Authenticity." This background gives him a unique perspective on the ever-evolving world of technology and its implications on society. He joined Android Police as a news writer in 2019. ![]() Manuel Vonau is Android Police's Google Editor, focusing on Android, Chrome, smartphone reviews, and other software Google products - the core of Android Police’s content. We kindly ask you to bear with us on this final touches. This is very inconvenient, we know, but we hope to find a solution soon.Īs per your additional feedback, we have informed our team and they have confirmed they are working on improving the search option and icon visualization. As of now, changes in names and icons made on one device after token addition, need to manually be replicated on all other devices linked to the account. We are aware that this would be the ideal situation and we are currently working towards that, but it is not yet available and we are not able to provide a timeline for this to be introduced. Unfortunately, the synchronization part is kind of a separate feature request. It's also working on improving the search experience and icon visualization. So far, it's not available, but the company is hoping to find a solution soon. We've reached out to Authy to ask about cross-device synchronization of custom logos.
