Why Use a Password Manager for SeaMonkey on macOS
SeaMonkey is a versatile, integrated Internet suite for macOS, combining web browsing, email, newsgroups, HTML editing, IRC chat, and web development tools. While powerful, it lacks many built-in conveniences of modern browsers—chief among them is seamless password generation, storage, and autofill. A dedicated password manager brings these advantages:
- Strong, Unique Passwords: Generate and store cryptographically secure, site-specific passwords without memorizing them.
- Centralized Vault: Access all your credentials, notes, and secure documents from one encrypted database.
- Cross-Device Sync: Sync passwords across macOS, iOS, Windows, Android and more, ensuring you have the right credentials anywhere.
- Autofill Auto-Save: Fill login forms automatically in SeaMonkey’s browser component, reducing typing and human error.
- Secure Sharing: Share selective credentials with family or team members with granular access controls.
- Two-Factor Zero-Knowledge: Many services offer built-in 2FA and operate under a zero-knowledge security model, so even the provider can’t read your vault.
