When logging into Salesforce from a new device or browser, users may be prompted to enter a verification code sent to their email or mobile device. This is part of Salesforce's Multi-Factor Authentication (MFA) and trusted login mechanisms to enhance account security.

However, in some environments (such as sandboxes, developer orgs, or internal-use orgs), repeated verification prompts can be inconvenient. Here’s how to reduce or remove these prompts safely and in compliance with Salesforce security policies.

5. Click New
6. Enter:

   • Optional: Add a description
7. Save
