5.4 Login without Password

TheloginWithCompanyName:companyEmployeeId:securityQuestions:passphrase:bayunAppCredentials:success:failure: function is the instance function that initialises your access to Bayun. The function takes the following parameters :

Let's say an employee has loginId [e-mail].

• companyName : Unique name of the company/tenant the authenticating employee belongs to, e.g. bayunsystems.com. This should be chosen using exactly the same methodology that was used during user registration via registerEmployeeWithoutPassword. Note that in some cases the email domain of the user could be different from the domain of the tenant this user belongs to. In such a case, the domain-name part of the tenant is what should be used as the companyName parameter.

• uiViewController : UIViewController of application.

• companyEmployeeId : EmployeeId unique within the company, e.g. [e-mail]. This should also be chosen using exactly the same methodology that was used during user registration via registerWithCompanyName:companyEmployeeId:email:bayunAppCredentials:authorizeEmployee:success:failure:. Note that while just the "username" portion might suffice in some cases, it is preferable to use the full loginId for consistency.

• securityQuestionsCallback : Most developers can just leave it null for default functionality. It is used for taking answers of Security Questions from the User. By default, the SDK uses AlertView to take User’s input for the answers of the Security Questions. The developer can optionally provide a custom UI block for taking User’s input, to match with the look-and-feel of the app, instead of relying on the default alert-view. If non-null, this block will need to take user answers to the security questions as an input and call validateSecurityQuestions method in the SDK. The Security Questions and QuestionIds are returned in the callback, in the form of NSArray<SecurityQuestion>.

• passphraseCallback : Optional block if passphrase is enabled. Most developers can just leave it null for default functionality. It is used for taking user passphrase input when passphrase is explicitly enabled by the user. By default, the SDK uses AlertView to take user input for passphrase if it is enabled for a user. However the developer can optionally provide a custom UI block to match with the look-and-feel of the app instead of relying on the default alert-view. If non-null, this block will need to take user passphrase as input and call Bayun validatePassphrase method for Passphrase validation.

• bayunAppCredentials BayunAppCredentials instance is initialized with AppId, AppSecret and Salt.

• success Success block to be executed after successful user login.

• failure Failure block to be executed if login fails, returns BayunError.

Validate Security Questions

Use validateSecurityQuestions function to validate the security questions' answers.

The function takes the following parameters :

• answers : NSArray<SecurityAnswer> with five objects.

• authorizeEmployeeCallback : Block to be executed if employee public key authorization is pending, returns employeePublicKey.

• success : Success block to be executed after successful Security Questions' Answers validation.

• failure : Failure block to be executed if security answers validation or registration fails, returns BayunError.

Validate Passphrase

Use validatePassphrase function to validate the passphrase.

The function takes the following parameters :

• passphrase : Passphrase to validate.

• authorizeEmployeeCallback : Block to be executed if employee public key authorization is pending, returns employeePublicKey.

• success : Success block to be executed after successful user passphrase validation.

• failure : Failure block to be executed if passphrase validation or registration fails, returns BayunError.
