Requesting Device Activation Status
To quickly determine in which state is the activation, you need to fetch its status.
Obtaining the Activation Status
To obtain a detailed activation status information, use the following code:
// Check if there is some activation on the device
if (await PowerAuth.hasValidActivation()) {
try {
// If there is an activation on the device, check the status with the server
const status = await PowerAuth.fetchActivationStatus();
switch (status.state) {
case PA2ActivationState.PA2ActivationState_PendingCommit:
// Activation is awaiting commit on the server.
console.log("Waiting for commit");
case PA2ActivationState.PA2ActivationState_Active:
// Activation is valid and active.
console.log("Activation is active");
case PA2ActivationState.PA2ActivationState_Blocked:
// Activation is blocked. You can display unblock
// instructions to the user.
console.log("Activation is blocked");
case PA2ActivationState.PA2ActivationState_Removed:
// Activation is no longer valid on the server.
// You can inform user about this situation and remove
// activation locally via "await PowerAuth.removeActivationLocal()"
console.log("Activation is no longer valid");
case PA2ActivationState.PA2ActivationState_Deadlock:
// Local activation is technically blocked and no longer
// can be used for the signature calculations. You can inform
// user about this situation and remove activation locally
// via "await PowerAuth.removeActivationLocal()"
console.log("Activation is technically blocked");
case PA2ActivationState.PA2ActivationState_Created:
// Activation is just created. This is the internal
// state on the server and therefore can be ignored
// on the mobile application.
console.log("Activation was created");
default:
console.log("Unknown state");
}
// Failed login attempts, remaining = max - current
const currentFailCount = status.failCount;
const maxAllowedFailCount = status.maxFailCount;
const remainingFailCount = status.remainingAttempts;
} catch (e) {
console.log("An error occurred, report it to the user");
}
} else {
console.log("No activation present on device");
}
Note that the status fetch may fail at an unrecoverable error PA2ErrorCodeProtocolUpgrade
, meaning that it’s not possible to upgrade the PowerAuth protocol to a newer version. In this case, it’s recommended to remove the activation locally.
To get more information about activation states, check the Activation States chapter available in our powerauth-crypto repository.
