Keygrain vs. Traditional Vaults

Different approach, different trade-offs. Traditional password managers like 1Password, Bitwarden, and LastPass store your passwords in an encrypted vault. Keygrain doesn't store anything — it derives passwords on the fly.

Feature	Keygrain	Traditional Vaults
Storage	Nothing stored — nothing to breach	Encrypted vault on servers (encrypted even if breached)
Account	No account needed	Requires account + master password
Sync	Optional encrypted sync — or none needed	Cloud sync with offline cache available
Recovery	No recovery if secret is lost — permanent	Recovery options exist (emergency contacts, reset flows)
Unique passwords	Deterministic — same inputs always produce the same output	Stored randomly generated passwords
Offline	Works fully offline	May need internet for sync or login
Cost	Free, open source	Ranges from free and open source (Bitwarden) to paid proprietary (1Password)
Password sharing	Not possible	Supported (family/team vaults)
Custom passwords	Not supported — passwords are deterministic	Fully supported

Who is Keygrain for?

• People who want zero trust — no server ever holds your passwords
• Users who need full offline access without cloud dependency
• Anyone uncomfortable with a single encrypted vault being a breach target
• Privacy-focused individuals who don't want to create accounts or share data

Who should use a vault instead?

• Teams and families who need to share credentials securely
• Anyone who needs custom passwords — some sites have unusual requirements that deterministic generation can't accommodate
• Users who want recovery options — if forgetting a secret with no way back is unacceptable, vaults offer emergency contacts, recovery keys, and reset flows
• People who store more than passwords — SSH keys, secure notes, credit cards, documents
• Anyone who relies on breach monitoring to know when credentials are compromised

There's no wrong choice — only different priorities. Many people use both: Keygrain for personal accounts, a vault for team credentials.
