If you've set a PIN yourself, you can choose how often you're required to enter a PIN from your lock screen, which can be anywhere from 30 seconds to 30 minutes, or each time you unlock your phone.

It depends on whether your employer requires a PIN for your Exchange email account or you created a PIN voluntarily.
Depending on your company's Exchange policy, your phone may reset to factory settings or lock up and make you wait to get back in if you repeatedly enter an incorrect PIN. To prevent this from happening accidentally, if you enter the wrong PIN several times, your phone will prompt you to enter a special phrase to continue. Once you enter the phrase correctly, you'll have one more chance to enter your PIN correctly, or your phone will be reset. For more info, see Protect my phone.Each company can choose from a variety of settings for PIN requirements, so if you're not sure how to unlock your phone or avoid resetting it, you'll need to talk to the support person at your company who manages your Exchange account.
If you've entered the wrong PIN 4 times, your phone will prompt you to enter a special phrase to continue. Once you enter the phrase correctly, you'll have one more chance to enter your PIN correctly, or your phone will restart and you can try again.
If you just aren't able to come up with the right PIN, you'll need to reset your phone to factory settings. Contact your mobile operator, check their website, or look through your phone's documentation to learn how to do that. For more info, see Protect my phone.
On Windows Phone 8 and Windows Phone 7, if you've entered the wrong PIN 5 times, the phone will be locked for 1 minute. If you enter another wrong PIN, it'll be locked for 2 minutes, then 4, then 8, and so on. If you just aren't able to come up with the right PIN, you'll need to reset your phone to factory settings. For more info, see Protect my phone.
Resetting your phone to factory settings will erase any settings and personal content you have on the phone, including texts, music, photos, videos, and apps.
If you didn't get a chance to back things up before resetting your phone, your mobile operator may be able to recover some info before you reset it. Contact your mobile operator for more details.
