5.4 Login without Password

The loginWithoutPassword function is the instance function that initialises your access to Bayun. The function takes the following parameters :

Let's say the user is logging-in using their login-id of [e-mail].

• sessionId : Unique sessionId.

  You can provide a unique sessionId to the loginWithoutPassword function call. If an empty sessionId i.e " " is provided, Bayun creates and returns a unique sessionId in the successful authentication response in successCallback.

  Same sessionId should be provided in all the subsequent calls to the Bayun APIs as an argument.

• 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.

• 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 registerEmployeeWithoutPassword. 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 API method in the SDK. The Security Questions and QuestionIds are returned through data of the callback, in the form of an ArrayList of HashMap with key "securityQuestions".

• 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.

• successCallback : Success block to be executed after successful user login.

• failureCallback : Failure block to be executed if user authentication fails, returns BayunError.

Validate Security Questions

Use validateSecurityQuestions function to validate the security questions' answers.

The function takes the following parameters :

• sessionId : Unique SessionId which is received in the login/registration function response.

• answers : Security questions' answers of type List.

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

• failureCallback : Failure block to be executed if user authentication fails, returns BayunError.

Validate Passphrase

Use validatePassphrase function to validate the passphrase.

The function takes the following parameters :

• sessionId : Unique SessionId which is received in the login/registration function response.

• passphrase : Passphrase to validate.

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

• failureCallback : Failure block to be executed if user authentication fails, returns BayunError.

Sample Code

JavaScript

const sessionId = "<sessionId>";
const companyName = "bayunsystems.com"; // company portion from loginId
const companyEmployeeId = "username";   // username portion from loginId

const securityQuestionsCallback = data => {
  if (data.sessionId) {
    if(data.authenticationResponse == BayunCore.AuthenticateResponse.VERIFY_SECURITY_QUESTIONS){
      let securityQuestionsArray = data.securityQuestions;
      //securityQuestionsArray is a list of Security Question Objects with questionId, questionText 
      // Iterate through securityQuestionsArray
      securityQuestionsArray.forEach(val=>{
        console.log(val.questionId);
        console.log(val.questionText);
      });
      //Show custom UI to take user input for the answers.
      //Call validateSecurityQuestions function with the user provided answers.
      
      //Here answers object is created just for reference
      var answers=[]; 
      answers.push({questionId: "<questionId1>", answer: "<answer1>"});
      answers.push({questionId: "<questionId2>", answer: "<answer2>"});
      answers.push({questionId: "<questionId3>", answer: "<answer3>"});
      answers.push({questionId: "<questionId4>", answer: "<answer4>"});
      answers.push({questionId: "<questionId5>", answer: "<answer5>"});
       
      const successCallback = data => {
        if (data.sessionId) {
          //Security Questions' Answers validated and LoggedIn Successfully
        }};
      
      const failureCallback = error => {
          console.error(error);
       };
       
       bayunCore.validateSecurityQuestions(data.sessionId, answers, null, successCallback, failureCallback);
    }
  }
};

const passphraseCallback = data => {
  if (data.sessionId) {
    if(data.authenticationResponse == BayunCore.AuthenticateResponse.VERIFY_PASSPHRASE){
      
     //Show custom UI to take user input for the passphrase.
     //Call validatePassphrase function with the user provided passphrase.
     
      const successCallback = data => {
        if (data.sessionId) {
          //Passphrase validated and LoggedIn Successfully
      }};
      
      const failureCallback = error => {
          console.error(error);
      };
       
      bayunCore.validatePassphrase(data.sessionId, "<passphrase>", null, successCallback, failureCallback);
    }
  }
};

const successCallback = data => {
  if (data.sessionId) {
    //LoggedIn Successfully
  }
};

const failureCallback = error => {
  console.error(error);
};

bayunCore.loginWithoutPassword(
      sessionId,
      companyName,
      companyEmployeeId,
      securityQuestionsCallback,
      passphraseCallback,
      successCallback,
      failureCallback
