Here is a simple tool that converts the Salesforce 15 character Ids to 18 character Ids.

This conversion of Salesforce ids from 15 character to 18 characters is done on the local machine and is safe to use.The Salesforce 15 to 18 char Id conversion tool calls Javascript from the footer of the page hence transmits no data to the server.

Enter the 15 character Salesforce Ids in the input text box (one per line) and click on the convert button to get the 18 character Salesforce Ids.

 
Input 15 character Salesforce Ids – one per line

 
Click to Convert Salesforce 15 digit Ids tp 18 digits
 
Output: 18 character Salesforce Ids

There are times when an Administrator needs to manually setup a users password in Salesforce. Salesforce Administrator’s can reset a User’s password from the User record detail page but Salesforce user interface doesn’t allow an Administrator to setup a specific password. Here is an Awesome Admin Hack to achieved this using the Developer Console or the Workbench.

Let’s discuss each method step by step.

Manually Setup a User’s Password in Salesforce Using the Developer Console.

Step 1. Get the User’s Id from the URL bar on the User’s record detail page.

Step 2. Open Developer Console

Step 3. Open the Execute Anonymous Window from Debug >> Open Execute Anonymous Window OR using the shortcut Ctrl + E

Step 4. Enter the following Apex code. Replace the UserId and Password with the actual values we need.

System.SetPassword('UserId','Password'); //Replace the UserId and Password

Step 5. Click Execute

We successfully manually setup the User’s password using the developer console and an email with the new security token will is emailed to the User.

Manually Setup a User’s Password in Salesforce Using Workbench.

1. Visit Workbench (https://workbench.developerforce.com/login.php) and Login using your Salesforce credentials.
2. Navigate to Utilities >> Password Management
3. Enter the User’s Id and the New Password
4. Click on Change Password

We successfully manually setup the User’s password using Workbench and an email with the new security token will is emailed to the User.

Pro Tip: Creating a User Interface to manually setup a User’s password in Salesforce.

Step 1. Create a New Text Field on the User Object and Name it Password__c

Step 2. Create the following trigger on the User object

trigger setPassword on User (before update) {
    for (User u:Trigger.New) {
        User oldUser = Trigger.OldMap.get(u.id);
        If ((u.Password__c != null) && (oldUser.Password__c != u.Password__c)) {
            System.SetPassword(u.id,u.password__c);
            //Uncomment below line to clear password field
            //u.Password__c = null;
        }    
    }
}

Note: Use validation rules on Password__c to only accept passwords that align with your organization’s password policies.

Here’s how the trigger looks in the developer console (image)

Step 3. Now visit the User’s record detail page and enter the new password in the Password field that we created and click Save.

The User’s password will be changed and an email with the new security token will be emailed to the User.

Update: To send the new password to the user by email, the trigger will be:

trigger CPTsetPassword on User (before update) {
    List <String> toAddresses = New List <String>();
    for (User u:Trigger.New) {
        User oldUser = Trigger.OldMap.get(u.id);
        If ((u.Password__c != null) && (oldUser.Password__c != u.Password__c)) {
            System.SetPassword(u.id,u.password__c);
            toAddresses.add(u.Email);
            //Uncomment below line to clear password field after reset
            //u.Password__c = null;   
            
            //Sending the users new password by email
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            mail.setToAddresses(toAddresses);
            mail.setSubject('Salesforce Password Reset');
            mail.setPlaintextBody('Your password was reset by the Administrator and the new Password is ' + u.Password__c);
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});         
        }    
    } 
}

Scenario:

While creating an Event or Task in Salesforce, the “Reminder” Checkbox is checked by default for all users. The reminders have piled up and making it difficult to keep track of the important events and tasks. The Sales team wants you to uncheck the “Set default event reminders to” Checkbox for all users.

This setting is found in:
My Settings >> Calendar and Reminders >> Activity Reminders >> ‘Set default event reminders to’

Solution:

This can be achieved by updating the User Object using Apex Code or the Data Loader

Executing Apex Code Method

A simple Apex code snipped can help us in unchecking “Set default event reminders to” Checkbox for multiple users. We will be using the Developer Console’s Execute Anonymous Window to run the Apex code.

To “Set default event reminders to” Checkbox to Unchecked, our Apex code will perform the following steps:

1. Step 1: Create a List to hold Users that need an update to their settings.
2. Step 2: Find all Active Users whose ‘Activity Reminder Checkbox’ is ‘Checked’ and add them to the above list.
3. Step 3: Iterate through each user in the above list and Uncheck the Activity Reminder Checkbox
4. Step 4: Create a final list to update to reduce the DML statements

// Create a list of Users whose setting needs to be changed
List <User> userList = New List <User>();

//SOQL to add all users to the above list
userList = [
    SELECT Id, UserPreferencesEventRemindersCheckboxDefault
    FROM User
    WHERE UserPreferencesEventRemindersCheckboxDefault = True AND ISACTIVE = True];

// Iterate through each user and update the setting
For (User u:userList) {
    u.UserPreferencesEventRemindersCheckboxDefault = False;
    userList2update.add(u);  //Add user to the final list to update
}

//Create a final list of Users to perform DML
List <User> userList2Update = New List <User>();


update userList2Update;  //Update the final List

Here’s the complete code to uncheck the “Set Default Reminders to” or any other user setting in Salesforce.

//Create a final list of Users to perform DML
List <User> userList2Update = New List <User>();
// Create a list of Users whose setting needs to be changed
List <User> userList = New List <User>();

//SOQL to add all users to the above list
userList = [
    SELECT Id, UserPreferencesEventRemindersCheckboxDefault
    FROM User
    WHERE UserPreferencesEventRemindersCheckboxDefault = True AND ISACTIVE = True];

// Iterate through each user and update the setting
For (User u:userList) {
    u.UserPreferencesEventRemindersCheckboxDefault = False;
    userList2update.add(u);  //Add user to the final list to update
}

update userList2Update;  //Update the final List

Now that we have the Apex Code, lets head to the Developer Console and execute this code from the Anonymous Window (Ctrl + E)
