TrustDevice-JS

A lightweight library for determining device uniqueness and risk identification.

Create a device identifier based on basic device information.

Will remain the same after uninstalling and reinstalling or clearing browser data.

🪧Attention🪧：The functions of the basic version of github are relatively limited.

You can visit AWS Marketplace or TrustDecision to learn about our professional version.
