Log in to Windows & Mac before you type a single key.

Your login details and credentials are as secure as you make them. The data is, of course, encrypted; the keys are generated randomly and automatically and are stored securely in your smartphone's keystore. You can further secure access to and use of your data with biometrics (Face ID, fingerprint, or PIN code) — and, of course, through your phone's automatic lock. What you don't need with Phrase-Lock is a questionable master password that you have to enter over and over again. Nor do you need an account with us.

With Phrase-Lock, you have more independence than with any other comparable system. Your login credentials are stored exclusively on your smartphone. It's entirely up to you whether or not to create backups and how you secure access to your smartphone. The only area where you aren't completely independent with a free license concerns the connection between your smartphone and your computer. With free licenses, this connection runs through our MQTT service — encrypted end-to-end with mTLS, so we cannot read or track the data traffic. You can also set up this connection yourself with a paid advanced license and a few scripts we provide free of charge.

Your smartphone and your computer have no direct way of communicating with each other — that would require open ports, which are a security risk. Instead, communication is routed through an intermediary that bridges the computer and the smartphone. We chose MQTT for its simplicity, high-quality open-source implementations, and multi-layer encryption (mTLS). If you'd like to run your own MQTT broker, there are no technical obstacles — we're happy to support you.

The Phrase-Lock Port installation provides a keyboard and a FIDO token without a physical USB connection — the devices are emulated. Think of it as a remote control for the keyboard and FIDO token, with your smartphone as the control center. We don't read anything, we don't track your browsing history, and Phrase-Lock works as soon as your computer wakes up from standby or a cold boot — allowing Windows Hello login immediately after booting.

Phrase-Lock is a European product developed and manufactured by iPoxo IT GmbH in Salzburg, Austria. To connect smartphones and computers, we rely on the open-source MQTT broker "mosquitto."

Phrase-Lock is free because we're driven by a mission: to empower every individual's digital sovereignty. The incentive we offer for a paid license is the ability to establish the smartphone-to-computer connection yourself, without our MQTT service.
