Splashtop Authenticator App: Set Up Two-Step Verification (2026)
Splashtop 2FA Needs an Authenticator App — Not SMS
If you are turning on security for Splashtop, there is one thing to know up front: Splashtop two-step verification (also called 2FA or multi-factor authentication) is built on TOTP authenticator apps, and text-message codes are not supported. Splashtop's own setup documentation states that two-step verification requires an authenticator app. So the first step is simply having a good one on your phone.
The fastest path on iPhone is a dedicated app. Authenticator App: 2FA scans the Splashtop QR code, stores the secret in a private on-device vault, and generates the six-digit code offline every 30 seconds — download it free from the App Store before you start.
How to Set Up Splashtop Two-Step Verification
- On your phone, install a TOTP authenticator app if you do not have one.
- Sign in to your Splashtop account and open the security or two-step verification settings.
- Enable two-step verification. Splashtop will display a QR code and a secret key.
- In your authenticator app, add a new account and scan that QR code (or choose manual entry and type the secret key).
- Enter the six-digit code your app generates back into Splashtop to confirm the pairing.
- Save the backup or recovery codes Splashtop gives you somewhere safe and offline.
That is the whole flow. From then on, each Splashtop sign-in asks for the current six-digit code from your authenticator app. You can tick "trust this device" on machines you control to reduce how often you are prompted.
Why a Dedicated Authenticator App Is the Right Choice
Because Splashtop protects remote access to your computers, the authenticator that guards it matters. A focused authenticator app has real advantages over scattering codes across tools:
- Works offline: codes are generated on the device, so you can sign in even without a connection.
- Separate from passwords: keeping codes in their own vault means one compromised account does not expose both factors.
- One home for every account: Splashtop, email, banking, and gaming logins live side by side, each as its own entry.
- Fast at sign-in: the current code is one tap away, with a countdown so you know when it refreshes.
Authenticator App: 2FA is built for exactly this on iPhone. It is a private, offline TOTP vault — see it on the App Store.
Business, Personal, and On-Prem
The authenticator-app requirement is consistent across Splashtop products. The setup steps are the same whether you use Splashtop Business, whose 2FA guide walks through pairing an app, or Splashtop Personal. Business accounts can additionally use a hardware key — Splashtop documents using a YubiKey — but for most people a TOTP app is the simplest, free option.
Don't Skip Backup Codes
Two-step verification means you need your authenticator to sign in, so plan for losing your phone. Save the backup codes Splashtop issues during setup, store them offline, and consider adding the same Splashtop secret to a second device you control. If you later switch phones, migrate your authenticator entries first — see our guides on moving authenticator codes to a new phone and recovering access after a lost phone.

Frequently Asked Questions
Which authenticator app works with Splashtop?
Any standards-based TOTP authenticator app works with Splashtop, because Splashtop two-step verification uses the standard time-based one-time password protocol. On iPhone, a dedicated app such as Authenticator App: 2FA scans the Splashtop QR code and generates the six-digit code you enter at sign-in.
Does Splashtop support SMS text codes for 2FA?
No. Splashtop's two-step verification requires an authenticator app; text messaging is not supported for the login code. You must pair an authenticator app to your Splashtop account to receive the six-digit codes.
How do I set up the Splashtop authenticator app?
Open your Splashtop account's security settings, enable two-step verification, then in your authenticator app add a new account and scan the QR code Splashtop shows (or enter the secret key by hand). Enter the six-digit code the app generates to confirm, and save your backup codes.
Can I use one authenticator app for Splashtop and my other accounts?
Yes. A single authenticator app can hold codes for Splashtop, email, banking, gaming, and more, each as a separate entry. Keeping them in one dedicated app — separate from your password manager — makes daily sign-in fast while keeping codes in their own vault.
What if my Splashtop code is rejected as incorrect?
The most common cause is a clock difference: TOTP codes are time-based, so if your phone's time is off by more than about 30 seconds the code fails. Enable automatic date and time on your phone, then try the newest code. See our guide on fixing Splashtop 2FA code errors for more.
