IMPORTANT: In July 2025, we stopped releasing new versions of KTX modules, and we removed the KTX libraries from the Firebase Android BoM (v34.0.0). If you use KTX APIs from the previously released KTX modules, we recommend that you migrate your app to use KTX APIs from the main modules instead. For details, see the FAQ about this initiative.

MultiFactorInfo

abstract class MultiFactorInfo : Parcelable

Known direct subclasses

PhoneMultiFactorInfo, TotpMultiFactorInfo

`PhoneMultiFactorInfo`	Represents the information for a phone second factor.
`TotpMultiFactorInfo`	Represents the information for a TOTP (time-based one-time password) second factor.

Represents a single second factor meant for the user. See direct subclasses for type-specific information.

FACTOR_ID_KEY

const val FACTOR_ID_KEY = "factorIdKey": String!

Public constructors

MultiFactorInfo

MultiFactorInfo()

Public functions

getDisplayName

abstract fun getDisplayName(): String?

Returns the user-given display name for this second factor.

getEnrollmentTimestamp

abstract fun getEnrollmentTimestamp(): Long

Returns the enrollment timestamp for this second factor in seconds since epoch (UTC midnight on January 1, 1970).

getFactorId

abstract fun getFactorId(): String

Returns the factor id of this second factor. You can match this with a generator factor id (e.g. FACTOR_ID) to determine to which direct subclass this can be cast.

getUid

abstract fun getUid(): String

Returns the unique identifier for this second factor.
