  Here is a code example for you:

  /**
   * Throws error if password strength is not met. Password must have:
   *  - 8 or more characters
   *  - uppercase and lowercase letters
   *  - at least one symbol
  **/
  const validatePassword: CollectionBeforeValidateHook = ({ data: { password } }) => {
    let message: string;
    if (password.length <= 8) message = 'Password must be at least 8 characters long';
  
    const hasUpperCase = /[A-Z]/.test(password);
    const hasLowerCase = /[a-z]/.test(password);
    if (!hasUpperCase || !hasLowerCase) message = 'Password must have both uppercase and lowercase letters')
  
    const hasSymbols = /[$-/:-?{-~!"^_`\[\]]/.test(password);
    if (!hasSymbols) message = 'Password must include at least one symbol.'
  
    if (message) throw new ValidationError([{ message, field: 'password'}]);
  };
  
  // if you don't have a users collection already you need to make one to set the beforeValidate hook:
  const Users: CollectionConfig = {
    slug: 'users',
    auth: true,
    hooks: {
      beforeValidate: [validatePassword],
    },
    fields: [],
  }

  Great question!
  This has to be done in a beforeValidate function on the auth collection.
