From a security perspective, which is safer?

It is difficult to give a definitive answer about what is safer without specific context. In general, safety depends on many factors: the technologies used, architecture, authentication and authorization methods, data protection, etc. For example, when choosing between storing passwords in plain text and hashing them with a salt — hashing is definitely safer. Or when choosing between HTTP and HTTPS — HTTPS is safer due to encryption.

If you specify which options you are referring to, I can provide a more specific answer.
