Password Complexity Indicator

The PasswordComplexityIndicatorService is for calculating the password complexity.

• Set default values in PasswordComplexityIndicatorService:

  • colors
  • texts
  • requirements

• How we set default values

  • colors: string[] = ['#B0284B', '#F2A34F', '#5588A4', '#3E5CF6', '#6EBD70'];
    
    texts: string[] = ['Weak', 'Fair', 'Normal', 'Good', 'Strong'];
    
    requirements: RegexRequirementsModel = {
      minLengthRegex: /(?=.{6,})/,                                        // Default min length 6
      numberRegex: /(?=.*[0-9])/,                                         // Default isContain number
      lowercaseRegex: /(?=.*[a-z ])/,                                     // Default isContainLowercase
      uppercaseRegex: /(?=.*[A-Z])/,                                      // Default isContainUppercase
      specialCharacterRegex: /[^a-zA-Z0-9 ]+/,                            // Default isContainSpecialCharacter
    };
    

• Make sure that the lengths of these values are equal (In our service we have 5 tests/colors/texts).

• The PasswordComplexityIndicatorService has only one method validatePassword that passes the password as an argument and returns the properties of the bar.

• The validatePassword method returns an object of the type ProgressBarStats.

• interface ProgressBarStats{
    bgColor: string,
    text?: string,
    width: number
  })
  

• Use this object to modify the password complexity bar

  • bgColor: decides the color of the bar.
  • text: explains the meaning of the bar to the user.
  • width: decides how full the bar will be.

How To Use

It's easy, imagine you have a password input that you want to add the complexity indicator under. Put this component under the input

  <abp-password-complexity-indicator [progressBar]="ProgressBarStatsObject"></abp-password-complexity-indicator>

• Pass the password to the validatePassword method of the PasswordComplexityIndicatorService, and bind return the value to the progressBar property of the abp-password-complexity-indicator
• We suggest localization instead of using the text value directly.
• en.json

    ....
    "Strength": "Strength",
    "Weak": "Weak!",
    "Fair": "Fair.",
    "Normal": "Normal.",
    "Good": "Good.",
    "Strong": "Strong!"
  

How To Customize

• If you want to change the test count, make sure that the lengths of the arrays of the colors,texts,regex in the PasswordComplexityIndicatorService are equal. Otherwise, it won't work.
• If you change any of the texts, you must change the localization file.
• That's it, you can start typing the password input!
