How It Works

1

Uses cryptographic pseudo-random number generator (CSPRNG) hardware entropy to eliminate any predictability.

Frequently Asked Questions

Far safer! Most websites generate passwords on a remote server where they can be logged. Alona Tool generates them purely inside your local browser memory.
