Multiple Android devices can be used:

The global unlock PIN function may be utilized on several Android smartphones and is not connected to any one particular device. Regardless of the device being used, this enables the user to have a reliable backup way for unlocking their devices.

Cons of Using a Universal Unlock PIN:

Probability of PIN guessing:

Another security issue with using a global unlock PIN is the chance that it may be guessed. A person who wishes to get unauthorized access to the device might quickly compromise the PIN if it is too basic or straightforward to guess. The chance of the PIN being guessed grows further if the user has used the same PIN across many devices or services.

PIN length possibilities are limited:

Some devices might only allow for a certain maximum PIN length, which can make it simpler for someone to guess the PIN. For instance, it could be simple for someone to predict the right combination through trial and error if the device only supports 4-digit PINs. The device’s and the data stored on its security may be jeopardised as a result.

Chance of forgetting PIN:

The chance for forgetting the PIN is yet another possible drawback of utilising a global unlock PIN.

Devices holding confidential or sensitive data should not be used:

Devices that hold sensitive or secret information, such as those supplied by businesses or the government, might not be ideal for an all-purpose unlock PIN. To protect the security of the device and the data stored on it in these circumstances, tougher and more secure authentication techniques, including biometric or multi-factor authentication, may be necessary.

Apps for banking or finances cannot be used:

To protect the security of financial transactions, some banking or financial apps could require more secure authentication techniques, such biometric authentication or two-factor authentication. For certain kinds of apps, a global unlock PIN might not be adequate, thus it cannot be utilized.
