Are you still troubled by the fact that you have too many passwords and often forget them? Number theft is a serious problem. The websites you visit and the various applications you use are under attack every day. Every time a security breach occurs, your password is stolen, and if you use the same password across apps and websites, hackers can easily gain access to your email, or even bank or other important accounts. Security experts recommend that you use a different random password for each account. But how to manage these passwords? pBox allows you to easily create, save and access your passwords. pBox encrypts and saves your password data locally, and your password data will not be transmitted over the network. You can also backup your password data to icloud, which will access your cellular network. Your password data is fully encrypted so only you can access it. Even if the app developer has this idea, there is no way to read your data. Your data is encrypted with AES-256-bit, salted hash, and SHA-512. The following actions will access your cellular network: -subscription -Restore your previous subscription - Backup to iCloud - Restore from iCloud Subscription Instructions: - The weekly subscription price is $1.99. - The monthly subscription price is $3.99. - The annual subscription price is $29.99. **iTunes account will be charged automatically at confirmation of purchase or auto-renewal unless the subscription is cancelled in iTunes Account Settings at least 24-hours prior to the end of the subscription period.
