If you must use a free phone-charging station, then you should run a Full Virus Scan on your device immediately after charging your phone. If the station was compromised, then the scan will indicate whether or not your phone was infected with malware. You should generally run frequent virus scans on your Android phone so you catch anything it may have picked up before it causes any damage.

The Dangers of Free Phone-Charging Stations

If you plug your phone into a hacked outlet, your data would be at risk. When the port has been tampered with by hackers and thieves, these sneaky professionals can take everything. After all, you use your Android phone for everything, so you have a lot of personal information on your device that you need to protect. You shop online with it, you store passwords, you access your bank account and your PayPal or Venmo accounts, and you apply for jobs online. Whatever data goes into it, hackers can steal.

Alternative Option: Use a Portable Battery

Avoid using a public charging station and opt to tote around a lightweight, portable charger instead. If you don’t use one of those portable devices, you are potentially putting your data at risk. You could also be introducing malware or viruses into your system. That’s the last thing you want to do.

First, you’ll need to purchase a portable charging battery. These easy-to-tote batteries come in all sizes. Compare the different models to see which one best suits your needs. They all have something different to offer. Take a look at how long it takes to charge the device, how long it takes to charge your phone, how long it can hold power, how much power it can hold, and if it has other uses (like if it can charge your laptop). Think about how large the item is and if it can be conveniently stored within your laptop bag, backpack, or purse.

1. Remember the Rules

Passwords should be at least eight characters long, and should be complex: they should contain lower case letters, upper case letters, numbers, and special characters. The longer you can make your password, the better.

2. Don’t be Too Obvious

Don’t create obvious passwords or PINs. PIN numbers like 0000, 1111, 2222, or 1234 are very common: up to 20% of those in use are accounted for by these common sets of numbers. Additionally, don’t be too personal with your password. Don’t use your phone number, your birth date, or your social security number when making your password.

3. Use a Passphrase

One of the biggest reasons people make simple passwords is that they want to make sure they will remember them. To remember your password while still being complex, use a passphrase. A passphrase could incorporate a line from your favorite movie, song, or television show while still using the rules of complexity detailed in rule #1. For example, your passphrase might be: “Sweet*H0me*Ala8ama.”

4. Use a Password Manager

If you have trouble remembering your passwords, use a password manager. With a password manager, like 1Password or LastPass, you’ll ensure that you have a unique and encrypted password that you can store safely on the cloud or transfer to your phone.

5. Don’t Use a One-Size-Fits-All Password

If a hacker figured out your password for one website, and you used the same password everywhere, he’d have all your information. That’s why it’s so important to create a unique password for every account that you have.
