30. Firebase: Good to know •Usage limits •Extending with Cloud Functions •Accounts import/export
31. Classic Email log in
32. What’s wrong You have to type You need to remember The password has to contain at least N characters. At least one character must be a number or a special character.
33. Autofill framework https://developer.android.com/guide/topics/text/autofill <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:autofillHints="password" />
35. SmartLock for Passwords https://developers.google.com/identity/smartlock-passwords/android/
36. SmartLock for Passwords • Increase in conversion rate • Significant drop in register and sign in failures https://developers.google.com/identity/smartlock-passwords/case-studies
37. How to Auth.CredentialsApi.save(mCredentialsClient, credential).setResultCallback( new ResultCallback() { @Override public void onResult(Status status) { if (status.isSuccess()) { // Credentials were saved } else { if (status.hasResolution()) { try { status.startResolutionForResult(this, RC_SAVE); } catch (IntentSender.SendIntentException e) { // Could not resolve the request } } } } });
38. RxSmartLock https://github.com/freeletics/RxSmartLock • Saving
 RxGoogleSmartLockManager.storeCredentials(context, credentials).subscribe()
40. RxSmartLock https://github.com/freeletics/RxSmartLock • Saving
 RxGoogleSmartLockManager.storeCredentials(context, credentials).subscribe() • Restoring
 RxGoogleSmartLockManager.retrieveCredentials(context).subscribe()
42. RxSmartLock https://github.com/freeletics/RxSmartLock implementation 'com.freeletics.rxsmartlock:rxsmartlock:1.0.2'
43. Fingerprint API • Secure • Fast • Easy
44. Fingerprint API: requirements • From API 26 • Fingerprint sensor • Enabled Lock screen • Registered fingerprints • Grant permissions
45. Fingerprint API: with prompt val callback = object: BiometricPrompt.AuthenticationCallback() { override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult?) { super.onAuthenticationSucceeded(result) } override fun onAuthenticationError(errorCode: Int, errString: CharSequence?) { super.onAuthenticationError(errorCode, errString) } } val prompt = BiometricPrompt.Builder(context) .setTitle(“Login") .setDescription("Use fingerprint to login") .setNegativeButton("Cancel", { }, { dialog, i -> }) .build() prompt.authenticate(CancellationSignal(), mainExecutor, callback) https://android-developers.googleblog.com/2018/06/better-biometrics-in-android-p.html API 28
46. Fingerprint API: with prompt val callback = object: BiometricPrompt.AuthenticationCallback() { override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult?) { super.onAuthenticationSucceeded(result) } override fun onAuthenticationError(errorCode: Int, errString: CharSequence?) { super.onAuthenticationError(errorCode, errString) } } val prompt = BiometricPrompt.Builder(context) .setTitle(“Login") .setDescription("Use fingerprint to login") .setNegativeButton("Cancel", { }, { dialog, i -> }) .build() prompt.authenticate(CancellationSignal(), mainExecutor, callback) https://android-developers.googleblog.com/2018/06/better-biometrics-in-android-p.html API 28

48. Fingerprint API: how to val callback = object: FingerprintManagerCompat.AuthenticationCallback() { override fun onAuthenticationError(errMsgId: Int, errString: CharSequence?) { super.onAuthenticationError(errMsgId, errString) } override fun onAuthenticationSucceeded( result: FingerprintManagerCompat.AuthenticationResult?) { super.onAuthenticationSucceeded(result) } } val fingerprintManager = FingerprintManagerCompat.from(context!!) fingerprintManager.authenticate(null, 0, CancellationSignal(), callback, null) https://developer.android.com/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat
