Classes

The following classes are available globally.

  • A concrete implementation of the TGFAuthenticator protocol that uses a user-provided passcode for FIDO2 user verification.

    This class manages the entire lifecycle of a passcode credential, including its creation, deletion, and modification. It uses a delegate pattern to request the presentation of a secure keyboard UI when user interaction is required.

    Declaration

    Objective-C

    
@interface TGFPasscodeAuthenticator : NSObject <TGFAuthenticator>

    Swift

    class TGFPasscodeAuthenticator : NSObject, TGFAuthenticator

  • A utility class for globally configuring the behavior of the Passcode Authenticator.

    @discussion By default, the FIDO2 SDK uses reasonable and secure settings. This class allows an application to customize certain behaviors, such as passcode complexity rules or keyboard appearance.

    @since 1.0.0

    Declaration

    Objective-C

    
@interface TGFPasscodeConfig : NSObject

    Swift

    class TGFPasscodeConfig : NSObject

  • An abstract base class for defining rules that a passcode must adhere to.

    @discussion This class is not intended to be used directly. Instead, create instances of its concrete subclasses (e.g., for length or complexity) and pass them to +[TGFPasscodeConfig setPasscodeRules:error:] to enforce a passcode policy.

    @since 1.3.0

    Declaration

    Objective-C

    
@interface TGFPasscodeRule : NSObject

    Swift

    class TGFPasscodeRule : NSObject

  • A concrete passcode rule that validates whether a passcode’s length falls within a globally configured range.

    This rule enforces minimum and maximum length requirements for user passcodes. The length constraints are configured globally using the class methods provided. If a passcode’s length is outside the minimumLength and maximumLength bounds, validation will fail with a relevant NSError.

    This class is a subclass of TGFPasscodeRule and is used to enforce a passcode policy.

    @since 1.3.0

    Declaration

    Objective-C

    
@interface TGFPasscodeRuleLength : TGFPasscodeRule

    Swift

    class TGFPasscodeRuleLength : TGFPasscodeRule

  • A concrete passcode rule that validates whether a passcode is a palindrome.

    This rule prevents users from creating weak passcodes that read the same forwards and backwards, such as “12321” or “5445”. If the validation fails, an NSError is generated with a domain and code specific to this rule violation.

    This class is a subclass of TGFPasscodeRule and is used to enforce a passcode policy.

    @since 1.3.0

    Declaration

    Objective-C

    
@interface TGFPasscodeRulePalindrome : TGFPasscodeRule

    Swift

    class TGFPasscodeRulePalindrome : TGFPasscodeRule

  • A concrete passcode rule that validates whether a passcode consists of a sequential series of digits.

    This rule prevents users from creating weak passcodes that are easy to guess, such as ascending (“123456”) or descending (“654321”) sequences. If the validation fails, an NSError is generated with a domain and code specific to this rule violation.

    This class is a subclass of TGFPasscodeRule and is used to enforce a passcode policy. @since 1.3.0

    Declaration

    Objective-C

    
@interface TGFPasscodeRuleSeries : TGFPasscodeRule

    Swift

    class TGFPasscodeRuleSeries : TGFPasscodeRule

  • A concrete passcode rule that validates whether a passcode consists of all identical digits.

    This rule prevents users from creating weak passcodes where all characters are the same, such as “111111” or “8888”. If the validation fails, an NSError is generated with a domain and code specific to this rule violation.

    This class is a subclass of TGFPasscodeRule and is used to enforce a passcode policy. @since 1.3.0

    Declaration

    Objective-C

    
@interface TGFPasscodeRuleUniform : TGFPasscodeRule

    Swift

    class TGFPasscodeRuleUniform : TGFPasscodeRule

  • Provides descriptive information about a FIDO2 authenticator.

    class TGFFido2ClientFactory : NSObject

  • Provides a global configuration point for the FIDO2 SDK.

    This class allows applications to customize security features and other behaviors of the SDK. By default, the SDK is configured for maximum security. Use the methods in this class to adjust settings like user verification policies, secure logging, and TLS Certificates.
