Sign In

What You See

When you open DavianVault for the first time (or after signing out), the Sign In screen appears. It shows:

• The DavianVault logo at the top
• The app name "DavianVault" and tagline "Zero-Trust Password Manager"
• Three security highlights:
  • AES-256-GCM Encryption — Military-grade encryption for all your data
  • Cross-Platform — Android, iOS, macOS, Windows
  • Zero Trust — Your data never leaves your device unencrypted
• A large "Sign in with Google" button
• A privacy notice: "Your credentials are encrypted locally. No application diagnostics logs are stored."

How to Sign In

1. Tap "Sign in with Google"
2. A Google sign-in screen appears — choose your Google account or enter your Google email and password
3. DavianVault receives your name, email, and profile photo from Google — it never sees or stores your Google password

What Happens Next

• If this is your first time using DavianVault with this Google account → you'll be taken to the Create Your Vault screen
• If you've used DavianVault before with this account → you'll be taken to the Unlock Your Vault screen
• If a cloud backup is found on your Google Drive from a previous device → the app restores it and asks you to unlock

If Something Goes Wrong

If sign-in fails, an error dialog appears with:

• A description of what went wrong
• Troubleshooting guidance based on the type of error
• A "Retry" button (for temporary errors like network issues)
• A "Close" button

Common causes: no internet connection, cancelled the Google sign-in, or Google Play Services is unavailable.

Important Notes

• Google Sign-In is required — it's used as your identity and enables cloud backup
• DavianVault never stores your Google password — authentication is handled entirely by Google
• Your vault data is completely separate from your Google account — Google cannot read it
