Two-Factor Authentication

Protect your account with a 6-digit code from an authenticator app, and recover access with backup codes.

3 min readUpdated July 16, 2026

Two-factor authentication (2FA) adds a second layer of protection to your account. After entering your password, you confirm a 6-digit code from an authenticator app on your phone — so even if someone learns your password, they can't get in.

2FA is available on the Business plan and above.

What you need

An authenticator app on your phone. Any TOTP-compatible app works, including:

  • Google Authenticator (iOS / Android)
  • Microsoft Authenticator (iOS / Android)
  • 1Password, Bitwarden, or another password manager with TOTP support

Signplanr never sends codes by SMS or email — the code always comes from your app.

Setting up two-factor authentication

  1. Go to Account → Security, or visit signplanr.com/account/security.
  2. Click Set up two-factor authentication.
  3. Open your authenticator app and scan the QR code. If you can't scan, enter the setup key shown below the QR code manually.
  4. Enter the 6-digit code your app shows and click Verify and enable.

As soon as 2FA is enabled, you'll see your backup codes. Save them before closing the dialog — they are only shown once.

Backup codes

When you enable 2FA, Signplanr generates 10 one-time backup codes. Each code can be used once in place of an authenticator code — they are your safety net if you lose your phone.

  • Copy or download the codes and store them somewhere safe (a password manager is ideal).
  • Your remaining code count is shown on the Security page.
  • You can regenerate a fresh set at any time — this invalidates all previous codes.

Logging in with 2FA

  1. Enter your email and password as usual.
  2. When prompted, enter the 6-digit code from your authenticator app.

If you don't have your device, click Use a backup code instead and enter one of your saved backup codes.

Trusted devices

Tired of entering a code on the same computer every day? Tick Trust this device for 30 days when entering your code. That browser will skip the two-factor prompt for 30 days, then ask again.

  • Trusted devices are listed on Account → Security, with when they were trusted and last used.
  • Revoke a device at any time — it will be asked for a code again within 15 minutes.
  • Revoke anything you don't recognise, and avoid trusting shared or public computers.
  • Disabling 2FA removes all trusted devices.

Recovering your account

Lost access to your authenticator app?

  1. On the 2FA prompt, choose Use a backup code instead.
  2. Enter one of the backup codes you saved during setup.
  3. Once you're in, go to Account → Security and either set up your new device or regenerate your backup codes.

Out of backup codes and no authenticator access? Contact your organisation owner, or email us at contact@signplanr.com from your account email address — we can verify your identity and reset 2FA for you.

Disabling two-factor authentication

  1. Go to Account → Security.
  2. Click Disable and confirm with a current code from your authenticator app.

Disabling 2FA deletes your backup codes. You can re-enable it at any time.

Tips

  • Save backup codes immediately — the most common lockout is a lost phone with no saved codes.
  • Use a password manager — apps like 1Password store the TOTP secret alongside your password, so a new phone doesn't lock you out.
  • Watch for the low-codes email — Signplanr emails you when you're down to your last couple of backup codes.
