If you enabled this security feature when you first set up your account, you'll be able to use your Apple ID to reset your password. This only works if this feature is enabled to begin with. If you have access to your Mac, you can turn this setting on by clicking the Apple menu and selecting "System Preferences." Click the "Users & Groups" option, then select your account. Click the padlock button to unlock the settings, then click "Allow user to reset password using Apple ID." This will appear after entering your password incorrectly three times. If this option does not appear, this function has not been enabled for your account and you'll need to use another method in this article. To reset your admin password, you'll need to enter your Apple ID password. This is the Apple ID that is associated with your Mac user account. After entering your Apple ID password, you'll be prompted to create a new admin password. You'll need to enter it twice to create it. You'll have to reboot your computer after creating a new admin password. Once your computer reboots, enter the new password you created to log in. When you log in after using your new password, you'll likely be prompted that your Keychain cannot be accessed. This is because the Keychain is only secured with your original admin password, and cannot be accessed with the new password for security reasons. You'll need to create a new Keychain for your passwords.

Summary: Try entering a wrong password three times. Click the link that appears to reset your password. Enter your Apple ID password. Create a new admin password. Use your new password after rebooting. Create a new Keychain.

If you use your J7 on either T-Mobile or MetroPCS, you may be able to unlock your phone by running an app that's already installed on your device. See Unlocking a Samsung J7 on T-Mobile or Unlocking a Samsung J7 on MetroPCS before proceeding with this method. There are 2 different ways to get an unlock code, and both require having this 15-16 digit ID. Tap the Phone app on your device to launch the phone keypad. Dial *#06# The number will display on the screen as soon as you enter the last # sign. Write this down so it's available. You can also find the IMEI in the Settings apptap "Status" and then scroll down to "IMEI." As long as your account is in good standing and you own your phone outright, your network provider should give you an unlock code without issue. When you call or chat with your provider, be ready to provide the IMEI. If you aren't able to get the lock code from your provider, you can pay an unlocking service to generate a code. These codes usually cost about $20, and can take around 24 hours to arrive in your email inbox. When choosing an unlocking service (there are many!), make sure it meets all the following criteria: Has a customer service phone number. Does NOT require you to install any software/apps. Has a refund policy if the code does not work. Has a legitimate website and a good reputation. You won't need to enter the unlock code until you've installed a SIM card from another provider. When you are ready to use your phone on your new network: Hold down the power button on your J7 and select "Power Off." Turn the phone over so you are looking at the back. Notice that there is a small divot at the top left of the phonethat's there to help you remove the back cover. Insert your fingernail into the divot and pull the cover gently away from the phone. You will see two card slots just above the batterythe SIM card is in the slot on the left side. Remove the battery: Insert your fingernail into the divot at the bottom right corner of the battery, then pull it outward. Gently slide the SIM card down until it's completely out of the metal holder. Put it aside. Slide the new SIM card into the slot, gold side facing down. Replace the battery and back cover. Press the power button to start your phone. You should see a message that says something like "Enter Unlock Code" or "SIM Network Unlock Pin." When the unlock code is accepted, you'll see a message that says "Network unlock successful." Once your phone is successfully unlocked, you'll be able to use it on your new network. If you see "Network Locked" and nowhere to enter an unlock code, dial #7465625*638*# (in the phone app) and then enter the unlock code when prompted.

Summary: Try using the Device Unlock app. Write down the IMEI number for your phone. Ask your cellular provider for the unlock code. Pay for an unlock code. Insert your new provider's SIM card. Power on the phone. Enter your unlock code.

The best time for a nap is between 12pm and 3pm, at which point your melatonin levels are highest and your energy level tends to be lowest. If you struggle with after-lunch drowsiness, grabbing a few minutes of nap can make you more productive and awake in the long-run, as opposed to gulping down an energy drink and trying to press on. Try to avoid naps after 4pm, especially if you struggle with insomnia. Sleeping too late in the day can make it harder to get to sleep at night, when you want to go to sleep. Grabbing 10-20 minutes of rest is usually best for a middle-of-the-day nap. More than that can leave you feeling drowsier than when you started, meaning you'll have to go through the whole waking-up process for the second time in the day. Alternatively, if you need a serious nap because you slept poorly the previous night, Try to aim for a full REM cycle of 90 minutes. Sleeping for 60 minutes can make you feel groggy for the rest of the day, whereas 90 minutes--a full sleep cycle--can leave you feeling refreshed. The idea of nodding off for too long can keep some people from actually falling asleep. Take the stress off and set an alarm, even if it's only 15 minutes from now, to wake you back up and get you back to whatever you've got to do. You can rest easy knowing you're not going to wake up when it's dark outside. Use your phone to set a quick alarm, or get a coworker to cover for you and knock on your door in 15 minutes. Then return the favor. While it may sound counterintuitive to drink a cup of coffee right before you go to sleep, caffeine's got to travel all the way through your digestive tract before you feel that caffeinated jolt--a process that takes about 20 minutes--so some pro nappers swear by the caffeine nap, which times itself perfectly with your wake-up. Down a quick cup of cold coffee just before nodding off and let the caffeine wake you up sharp and refreshed. It's still a good idea to set an alarm to keep yourself from sleeping too late.
Summary: Nap in the early afternoon. Keep it short. Set an alarm. Try a caffeine nap.
