Digital Security

For Normal People

Products

We are Determination Labs. As humans who happen to exist during the information age, we recognize how important it is to keep our digital lives secure. We also recognize that as humans, we are very forgetful beings. After all, password reset buttons exist for a reason. Why is this relevant? As technology continues to advance, it is becoming increasingly difficult to keep what matters safe. Development outpaces human adaptation, and when facing the future of an immutable and decentralized internet, password reset buttons might not be around to save us anymore. This is what we exist to solve. We dedicate ourselves to crafting digital security solutions with human-first thinking, so that normal people (not just those with technical skills) can easily protect what matters most, and to keep up with the never ending changes in technology.

NotAuth

Authentication Built for Normal People. Not an Authenticator or "NotAuth" is a cloud authenticator for two-factor authentication. Instead of relying on emails, usernames, or even passwords for its account system, NotAuth relies on biographic information processed with one-way cryptography. Personal information is never stored, enabling a passwordless and fully anonymous experience, protecting authenticator secrets with two layers of encryption.
