Introduction
Kraken is one of the most popular cryptocurrency exchanges globally, renowned for its security and advanced trading features. Safeguarding your login and configuration data is crucial for account recovery and maintaining uninterrupted access to your assets. In this guide, we’ll explore the best file formats to use when backing up Kraken login information, focusing on usability, security, and longevity.
1. JSON Format (.json)
Overview: JavaScript Object Notation (JSON) is a lightweight, human-readable format that stores structured data in key-value pairs.
Why Use JSON?
- Well-supported across programming languages and platforms.
- Ideal for configuration storage, including API keys and session details.
- Easily parsed and edited with text editors or custom scripts.
Use Case: Exporting Kraken API key configurations and preferences.
2. Encrypted Text File (.txt / .enc)
Overview: Plain text files are easy to create but should be encrypted when storing sensitive data such as passwords and 2FA secrets.
Why Use Encrypted Text?
- Highly portable and simple to manage.
- Encryption tools (like OpenSSL or GPG) ensure data confidentiality.
- Minimal dependencies for restoration.
Best Practice: Never store sensitive data unencrypted. Always password-protect backups and use strong encryption algorithms.
3. Encrypted ZIP Archives (.zip / .7z)
Overview: Compressed and optionally encrypted archives offer a convenient way to store multiple files.
Advantages:
- Combines multiple backup files (JSON, TXT, images of QR codes).
- Optional AES-256 encryption provides strong protection.
- Widely supported tools: 7-Zip, WinRAR, macOS Archive Utility.
Usage Tip: Keep encryption passwords secure and use unique filenames that don’t reveal file contents.
4. PDF Files (.pdf)
Overview: Portable Document Format (PDF) is useful for documenting backup information, especially printable copies of critical setup steps or QR codes for 2FA.
Why PDF?
- Human-readable, printable, and compatible across devices.
- Optionally password-protected for security.
- Great for storing static info like seed phrases or backup codes.
5. Secure Database Dumps (.sql)
Overview: For advanced users managing multiple accounts or automating setups, database dumps (from SQLite or MySQL) can store structured records.
Advantages:
- Ideal for large-scale, structured account data backups.
- Can be imported directly into applications or new environments.
Caution: Always encrypt dumps and limit access to sensitive fields (password hashes, API secrets).
Best Practices for Backups
- Always encrypt sensitive data using strong algorithms (AES-256 recommended).
- Keep multiple copies in secure, offline locations.
- Use hardware wallets for 2FA backup QR codes and secrets if possible.
- Document the backup process in a secure file to ensure easy recovery.
Conclusion
Backups are critical for Kraken login safety and account recovery. Depending on your technical proficiency and needs, a combination of formats (JSON for structured data, encrypted text or ZIP for portability, PDF for human-readable records) ensures both convenience and security. Implement strong encryption practices, and regularly test your backups to ensure reliability during emergencies.
