Because according to a study by an iPhone app developer, the most common passcodes are ridiculously easy to guess. iOS wizard Danial Amitay analyzed 204,508 passcodes and found that "1234" is far and away the most popular passcode, followed by "0000" and "0258" in a tight race for second.
According to the study, these are the most frequently used PINs: Four-digit PINs of the following kinds: 1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212.
For extra security, I'd recommend randomizing the capital letters, digits, and characters throughout the passcode. There's no technical limit on the length of iPhone's alphanumeric code, but six to ten characters is a good sweet spot.
The 10 most common passcodes used by iPhone users accounted for 15 percent of all the passwords analyzed, Daniel Amitay, the developer behind the iPhone app Big Brother Camera Security, said on his Website June 13. The most common values were: 1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212 and 1998.
For instance, the least popular combination, 8068, appears less than 0.001 percent of the time. Probably because it's so random—it follows no discernible pattern such as a date or repetition of numbers. “Statistically, 8068 is the safest PIN,” says Tyler Moffitt, senior threat research analyst at Webroot.
By default, iPhone passcodes are six digits, but Apple includes options to create a four-digit passcode, or a longer numeric or alphanumeric passcode. The default six-digit passcode is obviously more secure than any four-digit one, while the strongest passcodes use a combination of letters and numbers.
Data breaches over the years have repeatedly shown some of the most common passwords are "1234567", "password", and "letmein".
A strong 6-Digit PIN should not be predictable and cannot be easily guessed. We highly recommend that users choose a 6-Digit PIN that avoids these common pitfalls, as outlined below: No DOB (forward or backward) e.g. DDMMYY, YYMMDD, MMDDYY.
-The most popular PIN code (1234) is used more than the lowest 4,200 codes combined. - People have even less imagination in choosing five-digit passwords — 28% use 12345.
Apple requires that you use a strong password for your Apple ID—eight or more characters, including upper and lowercase letters and at least one number. Never share your Apple ID password, verification codes, or account security details with anyone. Don't use your Apple ID password with other online accounts.
An iPhone will disable for 1 minute after six failed passcode attempts in a row. The seventh incorrect passcode attempt will lock you out for 5 minutes, the eighth attempt for 15, and the tenth for an hour.
The “Find My iPhone” feature can help you unlock iphone without face id or passcode, but this method only works if Find My iPhone is turned on before the device is locked. In addition, you will need to remember the Apple ID and password of the locked iPhone.
If you enter the wrong passcode six times in a row, you'll be locked out of your device, and you'll receive a message that says iPhone is disabled. If you can't remember your passcode, you can erase your iPhone with a computer or with recovery mode, then set a new passcode.
When you enter an incorrect password 10 times, iPhone gets locked to avoid brute-force password crack. Hence, instead of making consecutive incorrect passcode attempts, you should learn how to reset iPhone forgot password to prevent your device from being disabled.
To unlock the iPhone before it gets completely locked out, you get 10 attempts to unlock with a passcode. No matter how agitated you're, if you have entered 4-8 wrong passcodes, you'll have to wait for 1-5 minutes. Whereas for 9 wrong attempts, 1 hour will render you the chance of attempting another try.
The safest 4-digit PIN is '8068' — or at least it was, until researchers at Data Genetics told everyone this week. The researchers there went through a set of 3.4 million four-digit personal identification numbers and found "8068" came up only 25 times.
Try to include numbers, symbols, and both uppercase and lowercase letters. Avoid using words that can be found in the dictionary. For example, swimming1 would be a weak password. Random passwords are the strongest.
