App Description
Protect your accounts easily with 2FA and the buhl: Authenticator
The authenticator app that doesn't want to know anything about you: The buhl:Authenticator protects your online accounts with two-factor authentication (2FA) – free of charge and without collecting any of your data.
A password is a lock. The buhl:Authenticator is the bolt behind it.
Your benefits:
• Free – no subscription and no hidden costs
• No data collection: The app doesn't collect any data about you
• Protection against phishing and account takeover with a second factor
• One-time codes (TOTP) for all services that offer 2FA via the authenticator app
• Add a new account in seconds via QR code
• Also protects your buhl:account, for example, for WISO Steuer (tax software)
• From Buhl in Neunkirchen – over 8.4 million customers trust Buhl
What is two-factor authentication?
With two-factor authentication, you need a second factor in addition to your password to log in: a security code that is generated only on your smartphone. The code is only valid for 30 seconds. Even if someone knows your password—for example, after a phishing email or a data breach—they can't access your account without this code.
It's that easy:
1. Activate two-factor authentication in your online account.
2. Scan the displayed QR code with the buhl:Authenticator.
3. Enter the 6-digit code from the app when logging in. Done.
One authenticator for all your accounts
The buhl:Authenticator works with all websites, apps, and services that support the TOTP method—for example, email accounts, social media, online shops, cloud storage, and password managers. Of course, it also works with your buhl:account, for example, for WISO Steuer.
Privacy that lives up to its name
We don't want to know anything about you. The buhl:Authenticator doesn't collect any data and doesn't track you. For something as important as your login data, rely on a German company: We operate our servers at our company headquarters in Germany – no third-party providers, no data going abroad.
Free
Some things shouldn't cost anything. Your security, for example. The buhl:Authenticator is completely free – no subscription, no in-app purchases.
