Firebase Cloud Messaging sends notifications and messages to devices which have installed specific Firebase-enabled apps. Adding support for FCM to an application requires multiple steps: add support to the Android Studio project, obtain registration tokens and implement handlers to identify message notifications.

For others, the application can implement an OCC layer outside of the database, and avoid waiting or silently overwriting records. In such cases, the form may include a hidden field with the record's original content, a timestamp, a sequence number, or an opaque token. On submit, this is compared against the database.
The receiver can use the public key (value of the p tag) to then validate the signature on the hash value in the header field, and check it against the hash value for the mail message (headers and body) that was received. If the two values match, this cryptographically proves that the mail was signed by the indicated domain and has not been ...
Authentication tokens (e.g., OAuth tokens) from web services stored in system storage for sharing between apps. Prior to Android 6.0 "Marshmallow", permissions were automatically granted to apps at runtime, and they were presented upon installation in Google Play Store. Since Marshmallow, certain permissions now require the app to request ...

In some instances, one may be asked to enter an access token (e.g. 40 random characters) rather than the usual password (it therefore should ...
As of November 2024, the OAuth 2.1 Authorization Framework draft is a work in progress. It consolidates the functionality in RFCs OAuth 2.0, OAuth 2.0 for Native Apps, Proof Key for Code Exchange, OAuth 2.0 for Browser-Based Apps, OAuth Security Best Current, and Bearer Token Usage. [10]
The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system. The mapping from original data to a token uses methods that render tokens infeasible to reverse in the absence of the tokenization system, for example using tokens created from random numbers. [3]
BlueTrace is an open-source application protocol that facilitates digital contact tracing of users to stem the spread of the COVID-19 pandemic. [2] Initially developed by the Singaporean Government, BlueTrace powers the contact tracing for the TraceTogether app. [3] [4] Australia and the United Arab Emirates have already adopted the protocol in their gov apps, [5] [6] [7] and other countries ...
