What format should an administrator use for the password reset email tag?

The correct format for the password reset email tag is {PASSWORD.RESET.URL}. This format is specifically designed to ensure that the system recognizes the tag correctly and dynamically replaces it with the appropriate password reset URL when sending out the email.

Using curly braces, as in the correct choice, is a typical convention in many systems for denoting a placeholder that will be substituted with actual data at runtime. This helps in maintaining clarity in the template since it clearly distinguishes placeholders from regular text. Other formats, such as brackets or parentheses, may not be recognized by the system as valid tags, which would result in the placeholder not being replaced, compromising the functionality of the password reset process.
