Non-custodial account recovery as easy as a normal password reset

Traditional methods to protect your users' assets can be confusing and risky for your customers. With Bunkyr, replace unwieldy and insecure recovery codes with something as easy as a social sign-in.

Users can easily recover encrypted assets without your systems ever having offline access

Limit your breach risk and give users ownership of their assets, without the burden of a seed phrase

Don't ask users to store recovery codes for years

Printed codes and mnemonics are prone to loss, or worse - they can fall into the hands of an attacker

Encryption keys generated from three distributed shares

Bunkyr never has access to user data and never stores keys

Datacenter-hosted cryptographic hardware generates a user's backup keys at request-time. Keys can only be generated if the end user, your systems, and Bunkyr all provide their portion of the key-derivation information.

Randomized user identifiers and zero user data, ever

Defense-grade cryptographic hardware

Reliable and scalable cloud-based SaaS API
