Why Build a Password Manager App?
Everyone needs a password manager but many people still reuse passwords. A clean, simple password manager app can serve users who find existing solutions too complex.
A password manager needs encrypted storage, strong password generation, search, categorization, and biometric authentication for quick access.
Fastshot generates a native password manager with encrypted vault, password generator, biometric unlock, and organized credential storage for iOS and Android.
