Free forever · A tool by MetricDeck

Your 2FA codes, one keystroke away.

Tick is a free two-factor authenticator for your computer. Type a few letters, press Enter, and the code is on your clipboard. No more reaching for your phone every time you sign in.

How it works

Type. Enter. Paste.

Signing in shouldn’t mean finding your phone, unlocking it, opening an app and typing six digits before they expire.

  1. git

    Type to find

    Start typing anywhere. Tick filters your accounts as you type, so the right one is always one or two letters away.

  2. Enter ↵

    Press Enter

    The current code is copied. If it’s about to expire, Tick hands you the next one so it never runs out mid-paste.

  3. ⌘V

    Paste and you’re in

    Paste into the login page. Tick clears the code from your clipboard a few seconds later.

Everything you need

Small tool. Thought through.

Scan QR codes off your screen

Setting up two-factor on a site? Tick reads the QR code straight from your screen. No phone, no camera.

Move from Google Authenticator

Export from Google Authenticator and scan the transfer code once. Every account comes across together. Aegis and 2FAS work too.

Works offline, installs like an app

Codes are maths on a secret and the time, so no internet is needed. Install Tick from the address bar and it opens like any other app.

Locks itself

Tick locks after a few minutes away and clears copied codes from your clipboard, so an unattended laptop isn’t an open door.

Fixes a wrong clock

Codes fail when your computer’s clock drifts. Tick notices and corrects for it, so your codes keep working.

Encrypted backups

Download an encrypted backup and restore it on any browser with your master password. Move to another app any time.

Security

Your codes never leave this browser.

Tick has no server and no account. There is nothing to breach, because there is nowhere your codes are sent.

Encryption
AES-256-GCM with a random 256-bit data key
Master password
PBKDF2-SHA256 with 600,000 iterations and a random salt. Never stored.
Storage
One encrypted record in your browser’s IndexedDB. Nothing readable touches disk.
Network
No server, no analytics, no third-party requests. A strict Content Security Policy blocks outside scripts.
Codes
Standard TOTP (RFC 6238), generated on your device and verified against the official test vectors.
While unlocked
The key lives only in memory and is dropped the moment Tick locks.

The honest trade-off

Two-factor is strongest when your codes live on a different device from your passwords. Keeping both in one browser trades a little of that separation for a lot of convenience. If you choose Tick, use a strong master password and keep your sites’ backup codes somewhere safe. There’s no password recovery, by design.

FAQ

Questions, answered.

How do I get my 2FA codes on my computer?

Open Tick in your browser, create a master password, then add each account by scanning the QR code from the site’s two-factor setup page or by importing from your phone’s authenticator. After that, type a few letters of the account name and press Enter to copy the current code.

Can I move my Google Authenticator codes to my computer?

Yes. In Google Authenticator, choose Transfer accounts, then Export accounts. Tick reads the transfer QR code with your computer’s camera or from a photo of it and imports every account at once. Tick also imports Aegis and 2FAS exports.

Is it safe to keep 2FA codes in the browser?

Tick encrypts your codes with AES-256-GCM using a key derived from your master password, keeps them only in your browser, and never sends them anywhere. The trade-off is that two-factor is strongest when codes live on a different device from your passwords, so use a strong master password and keep your sites’ backup codes somewhere safe.

Does Tick send my codes to a server?

No. There is no server and no account. Codes are generated on your device with the standard TOTP algorithm, and the encrypted vault is stored in your browser’s IndexedDB. Tick makes no third-party requests and runs no analytics.

Does Tick work offline?

Yes. Two-factor codes are calculated from a secret and the current time, so no connection is needed. Install Tick from your browser’s address bar to open it like an app, even without internet.

What happens if I forget my master password?

It cannot be recovered, because only you know it and nothing is stored on a server. Download an encrypted backup from Tick’s settings and keep your sites’ backup codes, so you can restore access if you ever need to start over.

Is Tick free?

Yes, Tick is completely free with no account and no limits. It is made and maintained by MetricDeck.
