What is a requirement for Dynatrace passwords regarding characters used?

The requirement for Dynatrace passwords to include a mix of uppercase and lowercase letters ensures that passwords maintain a certain level of complexity, which greatly enhances their security. Using both uppercase and lowercase letters contributes to making passwords harder to guess or crack through brute-force attacks, as it increases the overall number of possible combinations.

This requirement prevents the use of overly simplistic passwords that could be easily compromised. In modern security practices, mixed-case letters are commonly recommended to protect against unauthorized access and to comply with best practices for creating strong passwords. Additionally, incorporating different types of characters generally results in more secure password practices across various platforms.
