Why People Are Moving Away from OneTimeSecret
OneTimeSecret has been a popular choice for secret sharing since 2012. But in 2025, developers and security teams need more.
Limitations of OneTimeSecret free tier: - 7-day maximum expiry (paid feature for longer) - No IP allowlisting - No email access notifications - Ads on free tier - No security scoring

Why VaultSends Is the Better Choice
True Zero-Knowledge Architecture
VaultSends implements genuine zero-knowledge encryption. Your passphrase is never stored or transmitted — only a PBKDF2 hash for verification. Even if our servers were compromised, attackers would see only AES-256-GCM ciphertext with no way to decrypt it.
Enterprise Features, Free
IP allowlisting, email notifications, configurable expiry (5 minutes to 30 days), view count control (1 to 100), security scoring — all free, no account needed.
No Ads, No Tracking, Ever
VaultSends has no advertising, no tracking pixels, no analytics SDKs, no third-party scripts. Your secrets are not used to build a profile of you.
Conclusion
VaultSends offers a meaningfully better security profile than OneTimeSecret and PrivNote at the same price point (free). Try it at vaultsends.com — no account required.
