Pros and Cons
Evaluating the advantages and disadvantages of authy helps determine if it fits your security workflows.
Pros
- Encrypted cloud backup ensures you never lose access to your 2FA accounts.
- Multi-device sync lets you access tokens across phone, tablet, and desktop.
- Biometric and PIN locks provide an extra layer of local security.
- Works offline to generate codes without an internet connection.
- Entirely free to use with no premium tier.
Cons
- Cloud backup introduces a security tradeoff, as tokens are stored on Twilio servers.
- The software is closed-source, meaning it cannot be independently audited.
- Twilio discontinued the native desktop app in 2024.
- Offers less control than hardware keys like YubiKey for high-security use cases.
Who Is Authy For?
authy is best for users who want two-factor authentication backed by cloud storage and multi-device sync, solving the common problem of getting locked out of accounts when a phone is lost or replaced. Because it supports thousands of apps and works offline, it serves everyday security needs well.
Conversely, it is not for high-security users who prefer zero cloud storage. Individuals seeking zero-trust 2FA or complete transparency may prefer open-source alternatives like Aegis on Android or physical hardware security keys like YubiKey.
