How to choose 2fa & authenticators tools
Tools in this category split into three groups: authenticator apps for one person, hardware keys, and identity platforms that run 2FA for a whole team. These criteria separate them best:
- Who it's for. Ente Auth and 2FAS are personal authenticator apps. Okta and OneLogin are workforce identity platforms that handle SSO and MFA, and both have APIs for IT teams. Yubico sells physical keys for phishing-resistant login, for individuals and for enterprises.
- Pricing model. Ente Auth is free. 2FAS is freemium, with paid plans from $0.83/mo. OneLogin starts at $3/mo and Okta at $6/mo, and both offer free trials. YubiKeys are paid hardware.
- Open source and backups. Ente Auth and 2FAS are both open source. Ente Auth backs up your codes to the cloud with end-to-end encryption. 2FAS is local-first and works without an account.
- Platforms. Ente Auth runs on web, mobile and all three desktop systems. 2FAS covers iOS, Android, a Chrome extension and self-hosting. YubiKeys work on Windows, macOS, Linux, iOS and Android.

What should I look for in an authenticator?
