Security habits that matter
Treat generated secrets and decoded tokens as sensitive. Prefer unique values for every account or service, and never paste production secrets into shared chats.
Browser-side tools are convenient for inspection, but they do not replace proper storage, rotation, and verification in your systems.
- Use a password manager for storage
- Rotate secrets after accidental exposure
- Prefer long random values over short memorable ones
