Security Best Practices

  1. 01

    Generate

    Use long unique values for every account, app secret, and recovery workflow

    • Use at least 12 characters for passwords
    • Use 4-6 words for memorable passphrases
    • Use at least 256-bit secret material for JWT keys
  2. 02

    Check

    Review the generated value before using it in production or saving it to a vault

    • Avoid reused passwords and visible personal patterns
    • Prefer passphrases that are readable but still random
    • Keep secrets out of source code and screenshots
  3. 03

    Store

    Move the generated value into a secure place immediately after creation

    • Save account credentials in a password manager
    • Store production keys in environment variables
    • Enable two-factor authentication where available
  4. 04

    Maintain

    Rotate secrets when teams change, systems are exposed, or risk increases

    • Replace shared secrets after access changes
    • Watch account activity for unusual access
    • Retire old exports after import or migration
