How to Set Up Two-Factor Time-Based One-Time Password (TOTP) Authentication on iPhone Without Third-Party Apps

Unlocking an additional layer of safety to your iPhone is less difficult than you might suppose. With Two-Factor Time-Based One-Time Password (TOTP) authentication, you may bolster your device's protection and other website safety without relying on 1/3-party apps. Here's how you could set it up:

Field History Custom Component

 We have the standard history for our fields in salesforce. We can use that functionality from the related list. Here we will see that functionality using component and apex class. This will be a generic code for custom objects. Just paste the id of the record for which you want to see history. Make sure you have enabled history tracking for that object. 

Custom History

Here is the apex class for JSON. Save this first.


HistoryWrapper.cls


public class HistoryWrapper{

    public WrapperClass_attributes attributes;

    public String CreatedById;  

    public datetime CreatedDate;  

    public String Field;   

    public boolean IsDeleted;

    public string NewValue;

    public string OldValue;

    public String Id;   

    public Wrapperclass_CreatedBy CreatedBy;

    public static list<HistoryWrapper> parse(String json){

        return (list<HistoryWrapper>) System.JSON.deserialize(json, list<HistoryWrapper>.class);

    }   

    public class WrapperClass_attributes {

        public String type; 

        public String url;

    }    

    public class Wrapperclass_CreatedBy {

        public WrapperClass_attributes attributes;

        public String Name; 

        public String FirstName;    

        public String LastName; 

        public String Id;   

        }

    }


HistoryController.Cls

public class HistoryController{

    public string query{get;set;}

    public list<historywrap> recordsHistory{get;set;}

    public string objectLabel{get;set;}

    public HistoryController(){

        recordsHistory=new list<historywrap>();

        list<HistoryWrapper> parsedList=new list<HistoryWrapper>();

        id parentId=apexpages.currentpage().getparameters().get('id');

        if(parentId!=null ){

            string sObjName = parentId.getSObjectType().getDescribe().getName();

            Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();

            Schema.SObjectType ODSchema= schemaMap.get(sObjName);

            Map<String, Schema.SObjectField> fieldMap = ODSchema.getDescribe().fields.getMap();

            objectLabel= parentId.getSObjectType().getDescribe().getLabel();

            sObjName =sObjName.replace('__c','__history');

           

            if(schemaMap.get(sObjName)!=null){

                query='SELECT CreatedBy.name,CreatedBy.Firstname,CreatedBy.Lastname,CreatedDate,Field,IsDeleted,NewValue,OldValue ';

                query+='FROM '+ sObjName +' where parentId=\''+parentId+'\'   and (Field!=\'locked\' and field!=\'unlocked\') order by createddate desc';

                string outputget= JSON.serialize(database.query(query));

                parsedList=HistoryWrapper.parse(outputget);

                

                if(parsedList!=null && parsedList.size()>0){

                    for(HistoryWrapper ObjHistory :parsedList ){  

                        if(ObjHistory.Field=='created'){                        

                                 recordsHistory.add(new historywrap(ObjHistory.createdby.Name,ObjHistory.createddate,'Created','',''));                                                                                                       

                        }else if(fieldMap.get(ObjHistory.field)!=null &&  ObjHistory.newvalue!=null){ 

                            if(string.valueof(fieldMap.get(ObjHistory.field).getDescribe().getSOAPType())=='ID' ){

                                if (! Pattern.compile( '[a-zA-Z0-9]{15}|[a-zA-Z0-9]{18}' ).matcher( ObjHistory.newValue).matches() ){

                                      recordsHistory.add(new historywrap(ObjHistory.createdby.Name,ObjHistory.createddate,fieldMap.get(ObjHistory.field).getDescribe().getLabel(),ObjHistory.newvalue,ObjHistory.oldvalue));

Apex Code for Refresh Token and Token Generation for Interaction

Introduction: In Salesforce, interacting with external systems often requires the use of access tokens for authentication and authorization. To ensure secure and uninterrupted interactions, it is essential to handle token generation and refresh token functionality properly. In this blog post, we will explore Apex code examples for generating access tokens and implementing a refresh token mechanism to maintain secure and continuous communication with external systems. 1. Generating Access Tokens: To generate access tokens for interaction, you can use the OAuth 2.0 authentication protocol. The following Apex code demonstrates the generation of an access token using the Username-Password Flow: public class TokenGenerator {     public static String getAccessToken(String clientId, String clientSecret, String username, String password, String endpointUrl) {         HttpRequest request = new HttpRequest();         request.setEndpoint(e...
