Core Features​

Secret Phrase Setup​

• Users can enter a secret recovery phrase in their Account Details.
• Stored securely using:
  • Argon2ID hashing
  • Per-user salt using random_bytes(32) → 256-bit salt (automatically generated when user saves a secret phrase)
  • Per-user pepper, using random_bytes(16) → 128-bit pepper (automatically generated when user saves a secret phrase)

Entropy Validation​

• Secret phrase must meet minimum complexity:
  • At least 16 characters
  • At least 3 words
  • No more than 256 characters
