OVEX has an account lock feature to protect your account from an attack
OVEX has an account lock feature to protect your account from a Brute Force Attack. A brute force attack uses trial-and-error to guess login info, encryption keys, or find a hidden web page. Hackers work through all possible combinations hoping to guess correctly. This is an old attack method, but it's still effective and popular with hackers.
This is why your account will lock if there are too many failed password attempts. If this was a product of your doing you can easily unlock your account by clicking Resend account unlock instructions. Please see the below for reference:
You will then receive an email with a link to unlock your account.
