Yes, using a temporary email address is legal in most countries. It is simply a tool that allows users to protect their privacy.
However, legality depends on how the tool is used.
Using temporary email for legitimate purposes such as:
Protecting privacy
Testing software
Avoiding spam
Signing up for free trials
Is generally lawful. Using it for fraud, abuse, or illegal activity is not.
Like any technology, temporary email is neutral. Responsibility lies with the user.
