Decoy: Masked Email & Password by DecoyFF

Decoy is a privacy-first password and identity manager. Instead of handing every website your real email, Decoy fills a decoy email alias, a saved login, and 2FA codes inline — on any site, with one click.

• Decoy email aliases — give each site its own address; mail still reaches you.
• Inline autofill — logins, passwords, and 2FA codes, right in the page.
• End-to-end encrypted — everything is encrypted on your device. Decoy's servers store only ciphertext and can never read your data.
• Works with the Decoy iOS app — pair once, sync everywhere.
