A more thorough explanation:

Propter majorem securitatem is a Latin term used in law to mean "for greater security."

• A bank may require two forms of identification propter majorem securitatem when opening a new account.
• A company may implement stricter security measures propter majorem securitatem after a data breach.

These examples illustrate how the term is used to indicate that extra precautions are being taken to ensure greater safety or protection. In both cases, the entities are taking additional steps to prevent potential risks or threats.
