When transmitting passwords, what restriction is placed on their transmission?

When transmitting passwords, it's crucial to restrict their transmission primarily to secure domains to protect sensitive information from unauthorized access. The rationale behind ensuring that passwords are not sent outside a secure domain is rooted in security practices that aim to prevent interception by malicious entities. Limiting transmission to secure domains helps maintain the confidentiality and integrity of the information being protected.

While encryption of passwords is an important practice, sending passwords outside a secure domain poses a significant risk regardless of whether they are encrypted. Similarly, sending passwords in plain text or sharing them verbally increases vulnerability, as these methods can lead to easy access by unauthorized individuals. Keeping password transmission within a secure domain is essential for safeguarding access and ensuring that sensitive data remains protected from potential breaches.
