Google Authenticator alternatives
Last updated: 24 August 2026
Google Authenticator works, but it lives on one phone, ties accounts to a Google login, and makes leaving awkward. Here is an honest comparison of what else is available — including where a browser tool like this one genuinely fits, and where it does not.
Why people leave Google Authenticator
Google Authenticator does its job, but it has three properties that push people to look elsewhere.
- It lives on one phone. Lose the handset, or leave it at home, and every account it protects is out of reach until you find a backup code.
- It ties accounts to a Google login. If you keep a work Gmail and a personal Gmail, the app shows one set at a time. Reading a code from the other account means signing out and back in.
- Getting out is awkward. There is no export file, no readable backup, and no way to see the secret behind an account once it has been added. Its Transfer accounts feature produces a QR code in a format almost nothing else can read.
The realistic options
Another phone app
Aegis (Android) and 2FAS (both platforms) are open source, encrypt their storage, and export to a plain file you actually control. Authy offers multi-device sync, at the cost of trusting a company with your encrypted secrets. Any of these is a straight upgrade if you are happy staying on a phone.
A password manager
1Password, Bitwarden and similar can hold your two-factor keys alongside your passwords and fill both. Convenient, and genuinely well-engineered — but it puts both factors in one place, which weakens the point of having two. Reasonable for low-value accounts, debatable for your email or bank.
A hardware security key
A YubiKey or similar is the strongest option available. The secret never leaves the device and cannot be phished. The trade-offs are cost, carrying it, and needing a second one as backup.
A browser-based generator
A page that computes codes from a key you paste. No install, works on any device, and no dependence on a phone at all. The trade-off is real and worth stating plainly: you are trusting whoever serves that page. See below for how to reduce that.
Where a browser tool genuinely fits
It is the right tool when you need a code and your phone is not available, when you are moving between devices, when you want several accounts' codes visible at once, or when you work on a desktop all day and reaching for a phone forty times is friction you would rather not have.
It is the wrong tool as the only home for the secrets protecting your primary email or your money. For those, a hardware key or a dedicated app is safer, and any site that tells you otherwise is selling something.
The honest risk with any hosted page is that it can change after you have inspected it. Two things reduce that here: nothing is loaded from third-party servers, so there is less that can change underneath you; and the whole app can be downloaded as a single file and run from your own disk, offline, where nobody can alter it afterwards.
Moving your accounts across
Whatever you switch to, the hard part is extracting your accounts from Google Authenticator. The app can do it — Transfer accounts then Export accounts — but the QR code it produces packs many accounts into one binary payload that most tools cannot decode.
This generator reads that format directly, in your browser. One scan brings every account across with its name and settings intact. From there you can generate codes here, or re-export any account as a standard QR code and scan it into Aegis, 2FAS, 1Password or whatever you have chosen.

How to choose, briefly
- Highest-value accounts — email, banking, anything holding money: hardware key.
- Everyday accounts, phone-first: Aegis or 2FAS, with their export file backed up.
- Desktop workflows, or no phone available: a browser generator, with your keys backed up offline.
- Whatever you pick: keep the original setup keys somewhere durable. That backup, not the app, is what gets you back in.
Try it without committing anything
Nothing is stored unless you ask. Paste a key, see a code, close the tab and it is gone.
Common questions
What is the best alternative to Google Authenticator?
It depends on what you need. Aegis and 2FAS are the strongest phone apps because they are open source and export to a file you control. A hardware security key such as a YubiKey is the most secure option overall. A browser-based generator is the most convenient when a phone is not available or when you work on a desktop. For your highest-value accounts a hardware key or dedicated app is safer than any web page.
Can I use a web-based authenticator instead of an app?
Yes. Two-factor codes follow the open TOTP standard (RFC 6238), so any tool implementing it correctly produces the same code from the same setup key. A browser tool works for any account that offers authenticator-app 2FA. The consideration is trust rather than compatibility: prefer a tool that loads nothing from third parties and lets you download and run it yourself.
Is it safe to switch away from Google Authenticator?
Switching is not risky in itself, because exporting copies your keys rather than moving them. Google Authenticator keeps working after an export, so you can run both until you are confident in the new setup, then remove the old one. The real risk is having no backup of your setup keys at all.
Can I see codes from two Google accounts at the same time?
Not in the Google Authenticator app, because its accounts are tied to the signed-in Google account. Keys held in a browser generator are not tied to any account, so codes from a work Gmail and a personal Gmail can be shown together, grouped by source.
Do I lose my accounts if I stop using Google Authenticator?
No, as long as you have your setup keys or backup codes. The app does not own your accounts; it only stores the secrets. Export them first, confirm the new tool produces matching codes, and only then remove the app.
