Our verdict
2FAS suits anyone who wants a free authenticator that keeps codes and secrets on the device rather than in a cloud vault. Authenticator apps in this group start at a median entry price of €3, and 2FAS runs on iOS, Android and Chrome with a totp flow for everyday logins.

Pros and cons
Pros
- A free plan is included, so the totp codes work without a paid tier.
- Encryption is handled on the device with Secret Words, and end to end between the mobile app and the browser extension.
- Runs on iOS, Android and Chrome, covering the mainstream phone systems and browsers.
- Support runs on email, help centre and community, so a help centre and a community space answer common questions.
Cons
- Support is limited to email, help centre and community, with no phone line or live chat in the list.
- The listed features cover totp only, so the toolkit is narrower than the full password managers compared here.
- Desktop clients are missing from iOS, Android and Chrome, which lists phones and browsers.
Who it suits
- People who want a free authenticator and would rather keep codes on their own device
- Readers who prefer local encryption with Secret Words over a synced cloud vault
- Anyone pairing a phone with a browser and content with totp codes
Who should look elsewhere
- NordPass, if you want a web vault plus Windows, macOS and Linux apps rather than phone and browser coverage.
- Bitwarden, if you need a command line interface, desktop apps or an F-Droid build, none of which appear in iOS, Android and Chrome.
- Sinew Software Systems, if you want wearables listed among the platforms.
The company behind it
The service is run by Two Factor Authentication Service, Inc., based in the US and founded in 2015. That legal name is the one to check when comparing jurisdiction across tools in this category. Support comes through email, help centre and community, so a help centre and a community space sit alongside email rather than a phone line.

Frequently asked questions
Does 2FAS have a free plan?+
Yes, a free plan is included. The pricing page lists free and budget models, so a paid tier is optional rather than required for the core totp codes. That makes it easy to try the apps on iOS, Android and Chrome first and decide later whether an upgrade adds anything you need.
Is 2FAS a full password manager or just a code generator?+
The feature list covers totp, which centres on time-based codes rather than a full password vault. The apps on iOS, Android and Chrome are built for authenticating logins, so readers who mainly need a code generator can stay on the free plan.
How does 2FAS protect codes and secrets?+
Encryption happens on the device, with Secret Words guarding the local store, and the link between the mobile app and the browser extension is end to end encrypted. The totp codes are generated locally, which is why the platform list in iOS, Android and Chrome matters for a reader who moves between phone and desktop.
Which devices and browsers does 2FAS run on?+
The platform list covers iOS, Android and Chrome. That reaches the mainstream phone systems and the major browsers, with the mobile app pairing to the browser extension over an encrypted connection. Desktop-only workflows are the gap, since a dedicated Windows or macOS client does not appear in iOS, Android and Chrome.
How do entry prices compare with long term prices here?+
In the authenticator app group the median entry price is €3, while the median long term price is €2.84. Readers weighing what a renewal costs can set those against 2FAS, which lists free and budget models and a free plan.
What do I get if I upgrade to a paid plan?+
The pricing page lists free and budget models, and the free plan already covers the totp codes on iOS, Android and Chrome. A paid tier sits above that baseline, so it is worth checking whether the extra features are ones you would use before paying more.
Who runs 2FAS and where is it based?+
The operator is Two Factor Authentication Service, Inc., based in the US and founded in 2015. That name is what a jurisdiction check should look for, and it is the same entity named in the terms, so readers comparing tools in this category can match it directly.
How do I get help from 2FAS?+
Support runs on email, help centre and community. There is a help centre for self-service answers, a community space for other users, and email for direct questions. A phone line or live chat is not part of that list, so time-sensitive account issues go through email instead.
