What information should you store on your phone, you surely want them to be protected and safe, away from hackers who might use your personal identity theft data or to raise money from your bank account.
If you really want to protect yourself from hackers, install the updates for your operating system at the same time as they become available. But when you install apps for the phone, think well before you approve access to your data.
These instructions apply mostly to users of Android phones, because the procedure for checking the security of applications in Google is not as detailed and as strict as in Apple.
The basic recommendation is not to install anything from unknown and unverified pages. Even "safer" applications on your phone can turn into dangerous with the following updates. Therefore, it is best to take a few minutes while installing new applications to view all apps on your smartphone and check which of them have permission to use your data.
If someone steals your phone, your data may be compromised. Make sure your phone is locked when you are not using it.
If you are one of those people who plan in advance, the data will be safe and if your phone is stolen. One of the options is to activate the option on your phone to delete the data after several times the password will be erased. And in case this option seems too drastic, it's good to know that Google and Apple offer services that you can find your lost phone and manually locate or delete data.
Finally, never use the same password on multiple applications or services. Hackers routinely break into online services to steal user data that they then use on different websites. If you find it difficult to remember your passwords, use an application that will remember your passwords for you.
