Two-factor authentication (2FA) is a form of multi-factor authentication (MFA) that requires the user to provide proof of identification via two different means (often a password and a physical token). One of these factors is always your account’s password, and the other is typically a token with a limited lifetime generated by a hardware or software token generator.
Although both of these token-generation methods are effective and have their benefits and drawbacks, app-based 2FA is more convenient and accessible for most people because it is cheaper (or free) and more mobile.
However, there are a lot of 2FA apps on the App Store and the Play Store, making it difficult to choose one. To make things easier, we’ve compiled a list of the top two-factor authentication apps for both Android and iOS.
Two-Factor Authentication System
The Aegis Authenticator app provides two-factor security, but it’s only available for Android. It’s completely free and open-source. It can be used to generate authentication codes for many different services, even some that only support Google Authenticator.
Aegis’s compatibility with a wide variety of services stems, in part, from its support for the TOTP and HOTP algorithms. In a similar vein, the app’s ability to categorize tokens into groups and assign them individual icons makes it much simpler to locate certain tokens.
In addition, you can restrict screen captures, set automatic backups to the vault/cloud storage, and use biometric services to secure the app. The touch to reveal feature included in Aegis Authenticator hides your tokens until you tap on them.
If you’re switching to Aegis from another 2FA app, you can import your credentials with relative ease. You can choose between plain text and encrypted output when exporting your entries.

Authy for Twilio
Many Android and iOS users like Twilio Authy (formerly Authy) as their two-factor authenticator of choice. To further protect your online accounts, it creates robust 2-step verification tokens.
Authy does more than that, too; it safeguards your cryptocurrency wallets from the likes of Coinbase, CEX.IO, and others. It also functions without an active internet connection, so you’ll never have to worry about losing data.
When compared to other 2FA apps, Authy’s support for 8-digit tokens is a notable differentiator that may be used to take account security to a whole new level. In addition, Authy provides automatic backups to their servers, multi-device synchronization so that tokens may be accessed from any device, and safe cloud backups so that you never lose access to your tokens.
Twilio Authy, depending on the platform you’re using it on, allows you to secure the app using biometrics, a PIN, or a password, keeping your 2FA tokens safe from prying eyes.

A Microsoft Authenticator
The Microsoft Authenticator app for Android and iOS is a free, straightforward two-factor authentication solution. It’s compatible with a wide variety of online profiles, but as you might expect from Microsoft, it allows you to consolidate your various Microsoft accounts (whether for work, school, or personal use) into a single location.
Dual-factor authentication Microsoft Authenticator, like most 2FA apps, uses time-based tokens with a 30-second timer countdown. The TOTP technique used to generate these tokens ensures that the service continues to function even if you lose network connectivity.
Notification-based login for your Microsoft accounts is a standout feature of Microsoft Authenticator, allowing you to access your accounts with a single tap and no need to enter your password. Of course, the app’s security PIN or biometrics (fingerprint, facial authentication) will need to be used to verify your identity.
Additionally, the service enables cert-based authentication, which comes in handy when verifying the legitimacy of your device before gaining access to other Microsoft services and apps.

The Google Authenticator
The simplest two-factor authentication program is Google Authenticator. As its name suggests, it was developed by Google and is compatible with both Android and iOS devices. Google Authenticator’s widespread compatibility with other 2FA services and apps is one of its major benefits.
Google Authenticator is the way to go if you need a simple two-factor authentication program that doesn’t offer any extra capabilities (and is, in a sense, more secure owing to the lack of cross-platform and sync functionality). You can use it even if you don’t have an internet connection because, like most 2FA apps, it use the TOTP algorithm to create tokes. The HOTP algorithm is used by the app to produce tokens for use with supported services.
You can quickly and easily create an account by scanning a QR code or typing in a setup key. Similarly, QR codes make it simple to export your accounts. Protecting the app using biometrics is an optional extra layer of security.

Use two-factor authentication to keep your accounts safe.
The finest two-factor authenticator applications for Android and iOS are listed above, and they may be used to store and distribute 2FA tokens across several internet accounts.
The choice between these apps is ultimately up to you, even if they all function effectively and meet most of your demands. Obsidian, Authy, and 2FAS are three excellent choices for a 2FA software with cloud syncing and support for synchronizing across many devices.
On the other hand, Microsoft Authenticator is the superior 2FA option if you rely heavily on Microsoft services. On the other hand, since Google Authenticator doesn’t support syncing between devices or the cloud, it’s a safe pick if you’re concerned about security.
