What activity should you use to input a password in a web browser?

Using the "Type Secure Text" activity is ideal for inputting a password in a web browser because it is specifically designed to handle sensitive information like passwords. This activity ensures that the password is treated securely within the automation script.

When automating tasks, especially those involving credentials, it is crucial to protect sensitive data from being exposed in logs or scripts. The "Type Secure Text" activity not only masks the input during the operation but also ensures that it is not visible in plain text format, which minimizes the risk of unauthorized access or exposure.

In contrast, activities like "Type Text" would not provide this level of security, as they do not have mechanisms to conceal sensitive data. Meanwhile, options such as "Set Password" and "Insert Secure Credential" are not standard activities for direct input in web browsers but may be used in different contexts for managing credentials. Overall, "Type Secure Text" stands out as the best choice for securely inputting passwords during automation.
