Cognito UI text modifications

Unfortunately, with Amazon Cognito's Managed Login UI, it is not currently possible to directly modify or translate the text elements such as "Sign In" or "Username" that appear on the interface. The Managed Login UI provides a standardized authentication experience with limited customization options.

While Managed Login offers features like multi-provider authentication and a ready-to-use interface, it does not allow for the level of customization that would enable changing specific text elements or translating them to other languages.

If you need to customize the text or provide a localized version of the authentication UI, you may need to consider alternative approaches. These could include:

1. Building your own custom authentication UI using AWS Amplify, which would give you full control over the text and language used.

2. Using the Amazon Cognito API directly to handle authentication flows, allowing you to create a fully customized interface with your desired text.

It's worth noting that Amazon Web Services regularly updates its services, so it's advisable to keep an eye on AWS documentation for any future enhancements that might address this limitation in Managed Login customization.

Yes, you can customize the text in your Cognito Hosted UI!

Currently, there are two main approaches you can take:

1.Using the AWS Console (Recommended for basic customizations): Navigate to your Cognito User Pool Go to "App integration" → "Hosted UI customization" Here you can modify text through language customizations This is the quickest way if you just need to change basic text elements.

2. For more extensive customizations: You can use AWS Amplify UI components Or build a completely custom UI using Cognito APIs directly

For reference, here's the official AWS documentation that covers these options:
