How do I add a new 2FA account without pointing a phone camera?

When a website displays its 2FA setup QR code on your screen, take a screenshot or copy the image and drop, upload, or paste it straight into Secure TOTP's Add account view—or switch to the manual entry tab to enter the Base32 secret key directly.

Which TOTP settings and platforms are compatible?

Secure TOTP works with standard RFC 6238 configurations across GitHub, AWS, Google Workspace, Microsoft, Cloudflare, Shopify, WordPress, Stripe, Discord, and more—supporting SHA-1, SHA-256, and SHA-512 algorithms, 6-digit or 8-digit codes, and 30-second or 60-second intervals.

Is a browser extension better than a phone authenticator?

Neither workflow is strictly superior in every scenario. Browser authenticators minimize context-switching and eliminate manual typing errors at a desk, while dedicated mobile apps or hardware security keys physically isolate your second factor from your laptop OS. Many professionals use Chrome for everyday workflow accounts alongside a mobile copy or emergency recovery codes.

What a Browser Authenticator Extension Does—and How Management Works

Secure TOTP turns your Chrome toolbar into a self-contained TOTP vault with clean UX built for everyday developer, SaaS, and agency workflows.

Upload, Drag or Paste QR Screenshots

Skip phone cameras entirely. Drag, upload, or paste a 2FA QR screenshot right into Chrome, or enter Base32 secrets manually.

One-Click Code Copying

Click any active code row to place the 6- or 8-digit token in your clipboard with instant 'Copied' visual feedback.

Search & Filter Accounts

Instantly locate matching issuer names or account emails across large work and client portfolios.

Visual Countdown Timer

Each token displays remaining validity seconds cleanly so you avoid pasting expired codes mid-submission.

Edit Labels & View Usage History

Rename messy issuer labels, check added dates, last-used timestamps, copy counters, and underlying TOTP parameters.

Show/Hide Secret Inspection

Keep saved Base32 secrets masked by default and reveal a key intentionally only when transferring to a secondary app.

Secure TOTP Authenticator account details view showing added date, last used time, copy count, SHA-1 6-digit 30-second parameters, and Show secret button — Inspect algorithm settings, usage metadata & secret reveal: Track when each account was added, when a code was last copied, view algorithm parameters (SHA-1/SHA-256/SHA-512), and reveal saved secrets only when needed.

Browser Authenticator vs. Mobile Phone Authenticator

Understanding the practical workflow and risk differences helps you choose the right setup—or pair both intentionally.

Factor	Chrome Extension (Secure TOTP)	Smartphone Authenticator App
Speed at Desk	Instant toolbar open + one-click clipboard copy	Unlock phone, locate app, manually re-type 6 digits
Device Isolation	Shares your computer OS/browser boundary—requires strong PC hygiene	Physically separate device from desktop browser sessions
Offline Operation	Computes codes 100% offline using device clock	Computes codes 100% offline using phone clock
Account Import & Export	QR upload, Google Authenticator import, password-encrypted `.json` export	Camera scan; backup behavior varies by vendor (cloud sync vs QR transfer)
Supported Standards	RFC 6238 TOTP (SHA-1/256/512, 6/8 digits, 30s/60s)	Typically TOTP SHA-1 (some mobile apps ignore SHA-256/8-digit or HOTP)
