Twilio Authy vs Google Authenticator
Updated October 2026 · AppBreakup editorial
Twilio Authy
Twilio's free authenticator app with encrypted cloud backup and multi-device sync tied to your phone number.
Google Authenticator
Google's free authenticator app for Android and iOS, with optional code sync through your Google Account.
The short answer
Both are free phone authenticators that work with any site using standard codes. Authy suits people who want encrypted backups synced across several phones and tablets and accept registering with a phone number. Google Authenticator suits people who want something simple, with optional Google Account sync or no account at all. The biggest difference is leaving: Google lets you transfer codes, while Authy has never offered an export.
Twilio Authy or Google Authenticator: our take
Authy, owned by Twilio, built its following on backups. Your codes are stored in Twilio's cloud, encrypted with a backup password that Twilio never receives, and can sync to multiple phones and tablets. Your account is tied to your phone number, which is how you recover access on a new device. Google Authenticator added cloud sync later, through your Google Account; Google encrypts codes in transit and at rest, but it is not end-to-end encryption. Google also lets you skip the account entirely and keep codes on the device, moving them with a transfer QR code.
Platforms are now the same: both run only on Android and iOS. Twilio retired the Authy desktop apps in 2024, and Google has never offered one. Authy adds app protection with a PIN or biometrics; Google's app is more basic in organisation and export.
The practical sticking point is portability. Authy has no way to export your codes, so moving to another app means re-enrolling each account one by one. A 2024 incident that exposed phone numbers linked to Authy accounts also made some users uneasy about the phone-number requirement. Google Authenticator's transfer QR code makes switching phones or apps easier.
Choose Authy if automatic backup across several devices, encrypted with a password only you know, matters most and you are comfortable with phone-number registration. Choose Google Authenticator if you want a simple app you can use without an account, or already trust Google with your data. If you are starting fresh and care about export, it is worth also looking at open-source options.
Which should you pick?
Choose Twilio Authy if…
- People who want automatic encrypted backup across phones and do not mind phone-number registration
- Encrypted cloud backup with a password Twilio never sees
- Syncs across multiple phones and tablets
Choose Google Authenticator if…
- People who want a simple, free authenticator and are comfortable with Google syncing their codes
- Free and very widely supported
- Optional cloud sync through your Google Account
About each app
What is Twilio Authy?
Authy, owned by communications company Twilio, became popular because it solved the lost-phone problem early: codes are backed up to Twilio's cloud, encrypted with a backup password that Twilio never receives, and can be synced to several phones and tablets. Accounts are registered to your phone number, which is used to recover access on a new device. It generates standard TOTP codes for any site and supports app protection with PIN or biometrics. The app is free. Twilio retired the Authy desktop apps in 2024, so it now runs only on Android and iOS, and it has never offered a way to export your codes, which makes leaving it tedious: you generally have to re-enrol each account in a new app. A 2024 incident in which phone numbers linked to Authy accounts were exposed also raised privacy concerns. It still works well for people who value automatic backups, but many now prefer apps with export and no phone number requirement.
What is Google Authenticator?
Google Authenticator is the app most people meet first when a site asks them to set up two-step verification, and many sites still mention it by name. It generates standard time-based and counter-based one-time codes for any service that supports authenticator apps, not just Google, and codes work without an internet connection or mobile signal. Since 2023 it can sync your codes to your Google Account, so they survive a lost or replaced phone; Google says codes are encrypted in transit and at rest, but this is not end-to-end encryption, so Google holds the keys. You can also choose to use it without an account and keep codes on the device only, and move them to a new phone with a transfer QR code. It is free with no ads or paid tier and runs on Android and iOS. The app is deliberately basic: there is no desktop version, few organisation features and limited export options compared with open-source rivals.
