Instagram Authenticator Code Not Working or "Invalid": How Do I Avoid Getting Locked Out?

Instagram says your authenticator app code is invalid? The common causes, like time sync, and how to avoid locking yourself out.

Cover card with a phone and clock icon, for an Instagram authenticator code that says invalid.

Short answer

If Instagram rejects your authenticator code, the most common cause is your phone's clock being out of sync, so turn on automatic date and time. Make sure you're using the code for the right account, and enter it before it changes. If you're locked out, use a backup code or the 'try another way' option. Don't repeat many attempts.

Summary

Time sync is the most common cause.
Check the code is for the right account.
Use backup codes if you saved them.
Try another way offers other options.
Too many attempts can lock you out temporarily.

App reinstalled without backup	Use backup codes

#What if I'm locked out?

#What common mistakes should I avoid?

Repeated attempts in a row.
Not saving backup codes.
Deleting the authenticator app.
Sharing codes with anyone.

#When should I ask an expert before I act?

Ask for help before you appeal if the account matters to your income, your business or your memories, if you have already had one appeal rejected, or if you cannot tell whether the problem is a bug, a restriction or a hack. That is where most avoidable losses happen.
