FAQ: Seed Phrase Security in 2025

Q: Can I store my seed phrase in password managers?
A: Only use quantum-resistant managers with zero-knowledge architecture. Conventional cloud storage remains high-risk.

Q: How often should I rotate backups?
A: Update physical storage locations every 6 months. Refresh encryption methods annually.

Q: Are biometric wallets safe for seed phrases?
A: Only when combined with multi-factor authentication. Standalone biometrics can be spoofed.

Q: What happens if quantum computers break encryption?
A: Use post-quantum cryptography (PQC) algorithms like CRYSTALS-Kyber for future-proofing.

Q: Can family members help secure my seed phrase?
A: Implement multi-sig inheritance solutions instead of direct sharing. Most 2025 thefts involve trusted parties.
