Secure Key and Password Storage:
Never Store Private Keys Digitally in Plaintext
Most digital storage (like a .txt or .doc file) is vulnerable to malware, cloud sync hacks, and accidental sharing.
How to Store Private Keys Physically:
- Good: Write it down by hand on acid-free paper using a permanent pen
- Better: Stamp it by hand into metal plates
- Make copies and store in different - secure - physical locations
- Make split copies - Physical Cold Storage
-
Avoid:
- Taking photos or screenshots
- Printing from a Wi-Fi-enabled printer
If You Must Store Digitally:
- Use KeePassXC
- Use password manager
- Never use plugins or browser extensions with anything security related
Website Safety:
Never enter private keys on unknown or untrusted websites. Check:
- Is the site HTTPS encrypted?
- Is the domain exactly correct? (Beware phishing lookalikes)
- Do you trust the site's developers?
- Consider using read-only wallets (watch-only) for tracking instead of exposing your key
