Customaize UI placeholder messages & error messages based on query params

Question

Hi,
Is there's any way to customize the default placeholder messages and error messages in the login form

We're customizing this screen using query params, as a single B2C tenant is used across multiple apps, and it's not possible to create and upload policy for each app.

Hello @Yogesh Agrawal · Thank you for reaching out.

Please find below the parameters to customize the messages, you have highlighted in your question.

<LocalizedString ElementType="ErrorMessage" StringId="UserMessageIfClaimsPrincipalDoesNotExist">The username or password provided in the request are invalid.</LocalizedString>  
<LocalizedString ElementType="ErrorMessage" StringId="UserMessageIfInvalidPassword">The username or password provided in the request are invalid.</LocalizedString>  

With above parameters, for both invalid username and invalid password, it will return same message, which is "The username or password provided in the request are invalid."

    <LocalizedString ElementType="UxElement" StringId="required_field">This information is required.</LocalizedString>  

above parameter can be used to customize "This information is required." message.

Use UserHelpText parameter for the pre-populated text in a given text box, under the claims schema where the sign in and password claims are defined. Please refer to UserHelpText parameter in the examples documented here: ClaimsSchema
