Gdy zapisujesz dane logowania przy użyciu Smart Lock na urządzeniach z Androidem O
lub nowszej, Smart Lock używa natywnego okna potwierdzenia autouzupełniania zamiast własnego
gdy tylko jest to możliwe. (Pamiętaj, że dane logowania zapisane przy użyciu autouzupełniania z
Dane Google są dwukierunkowe udostępniane funkcji Smart Lock na hasła).

To ensure the continued security and usability of your app, [migrate to\n| Credential Manager](https://developer.android.com/training/sign-in/passkeys/) today. Credential Manager supports passkey, password, and federated identity authentication (such as Sign-in with Google), stronger security, and a more consistent user experience.\n\nAfter users successfully sign in, create accounts, or change passwords, allow\nthem to store their credentials to automate future authentication in your app.\n\nBefore you begin\n----------------\n\n[Configure an Android Studio project](/identity/smartlock-passwords/android/get-started).\n\nStore credentials\n-----------------\n\nCreate a `Credential` object containing a user's sign-in information. For\nexample, to let users store their credentials after successfully signing in with\ntheir passwords: \n\n Credential credential = new Credential.Builder(email)\n .setPassword(password) // Important: only store passwords in this field.\n // Android autofill uses this value to complete\n // sign-in forms, so repurposing this field will\n // likely cause errors.\n .build();\n\nOr, for example, after users successfully\n[sign in with their Google account](/identity/sign-in/android/people): \n\n GoogleSignInAccount gsa = signInTask.getResult();\n Credential credential = new Credential.Builder(gsa.getEmail())\n .setAccountType(IdentityProviders.GOOGLE)\n .setName(gsa.getDisplayName())\n .setProfilePictureUri(gsa.getPhotoUrl())\n .build();\n\nThen, call [`CredentialsClient.save()`](/android/reference/com/google/android/gms/auth/api/credentials/CredentialsClient#save(com.google.android.gms.auth.api.credentials.Credential)) to save users'\ncredentials. If the call to `CredentialsClient.save()` is not immediately\nsuccessful, the credentials might be new, in which case the user must confirm\nthe save request. Resolve the `ResolvableApiException` with\n`startResolutionForResult()` to prompt the user for confirmation.\n\nIf the user chooses not to save credentials, the user won't be prompted again to\nsave any account's credentials for the app. If you call\n`CredentialsClient.save()` after a user has opted out, its result will have a\nstatus code of [`CANCELED`](/android/reference/com/google/android/gms/common/api/CommonStatusCodes#CANCELED). The user can opt in later from the Google\nSettings app, in the Smart Lock for Passwords section. The user must enable\ncredential saving for all accounts to be prompted to save credentials next time. \n\n mCredentialsClient.save(credential).addOnCompleteListener(\n new OnCompleteListener\u003cVoid\u003e() {\n @Override\n public void onComplete(@NonNull Task\u003cVoid\u003e task) {\n if (task.isSuccessful()) {\n Log.d(TAG, \"SAVE: OK\");\n Toast.makeText(activity, \"Credentials saved\", Toast.LENGTH_SHORT).show();\n return;\n }\n\n Exception e = task.getException();\n if (e instanceof ResolvableApiException) {\n // Try to resolve the save request. This will prompt the user if\n // the credential is new.\n ResolvableApiException rae = (ResolvableApiException) e;\n try {\n rae.startResolutionForResult(this, RC_SAVE);\n } catch (IntentSender.SendIntentException exception) {\n // Could not resolve the request\n Log.e(TAG, \"Failed to send resolution.\", exception);\n Toast.makeText(activity, \"Save failed\", Toast.LENGTH_SHORT).show();\n }\n } else {\n // Request has no resolution\n Toast.makeText(activity, \"Save failed\", Toast.LENGTH_SHORT).show();\n }\n }\n });\u003c/pre\u003e\n\n @Override\n public void onActivityResult(int requestCode, int resultCode, Intent data) {\n super.onActivityResult(requestCode, resultCode, data);\n\n // ...\n\n if (requestCode == RC_SAVE) {\n if (resultCode == RESULT_OK) {\n Log.d(TAG, \"SAVE: OK\");\n Toast.makeText(this, \"Credentials saved\", Toast.LENGTH_SHORT).show();\n } else {\n Log.e(TAG, \"SAVE: Canceled by user\");\n }\n }\n\n // ...\n\n }\n\nAfter storing credentials, retrieve them by calling\n[`CredentialsClient.request()`](/android/reference/com/google/android/gms/auth/api/credentials/CredentialsClient#request(com.google.android.gms.auth.api.credentials.CredentialRequest)).\n\nTargeting Android O and above\n-----------------------------\n\nWhen you save password credentials using Smart Lock on devices running Android O\nor newer, Smart Lock uses the native autofill confirmation dialog over its own\ndialog whenever possible. (Note that credentials saved using Autofill with\nGoogle are bi-directionally shared with Smart Lock for Passwords.)"]]
