MyPasswordStrength.NET.MAUI 1.0.0

MyPasswordStrength.NET.MAUI

A .NET MAUI library for validating password strength based on customizable complexity requirements.

Background

Define your password strength complexity requirements with ease using the library.

The package provides a PasswordStrengthEntry Entry that you can use to validate passwords in your .NET MAUI applications.

You can set the password strength requirements through the properties of the MyPasswordStrengthOptions class and pass the options to the Entry.

The special characters considered in the validation are: @$!%*?&.

You can modify this set of special characters by setting the SpecialCharacters property of the options to a custom string of special characters.
