Currently, if you get locked out of your account, the recovery process is a manual one …
You have to fill out a support form then await a response from the security team. Engadget says that Instagram account recovery is set to be automatic.
The updated approach uses the app to ask for different types of information (such as your original email address or phone number). You’ll then get a six-digit code sent to the contact information of your choice, and Instagram will then stop hackers from using email or phone number codes to take over your account from a different device.
This new technique would make sure that you could recover your account even if an intruder has changed the user name and contact information.
To make it less likely that bad actors will decide to take over your account in the 1st place, a new protection is being put in place.
Instagram is providing a safeguard that ensures a user name can’t be claimed for a “period of time” after account changes, whether or not it’s a hack or a voluntary change.
It’s not certain when the in-app recovery will be widely available, though the user name lockdown is available to all android users now and deploying to iOS users.
