opt-in
A pattern in security design in which a security feature must be actively configured and enabled by the user, with the default state being disabled. In security-sensitive scenarios, opt-in is generally considered less safe than secure by default, because most users do not actively modify default configurations.

The opt-out default-consent mechanism assumes consent unless the data provider actively refuses, in contrast to the opt-in mechanism; according to criticism, Meta did not simultaneously provide a clear refusal entry point during the transition period.
Opt-in means the feature is not enabled by default and must be explicitly turned on by the developer, as opposed to opt-out (enabled by default and can be actively disabled)
Opt-in means secure behavior requires users to actively enable it, and the default state is insecure; secure by default requires the system to maintain the most conservative, safest posture even when the user configures nothing.
Opt-in requires users to actively consent before data collection is enabled, whereas the opt-out model adopted by most automakers turns collection on by default and only allows users to actively disable it after the fact.
A truly user-respecting data handling practice should be 'off by default, ask explicitly' (opt-in rather than opt-out).
