# Updating registry settings in Amazon ECR public
Updating registry settings

Your public registry provides settings to configure a custom alias and display name.

By default, your public registry is assigned a **default alias** after your first public repository is created. You can request a **custom alias** for your registry, and if approved, both the default alias and custom alias can be used to access your public repositories. The registry **display name** appears on each repository in the Amazon ECR Public Gallery as well.

When requesting a custom alias, the following words or phrases should be avoided:
+ An alias that includes `aws`, `amazon`, or the name of an AWS service
+ An alias using a company name for which you do not have permission to use
+ Generic names, such as `test`, `public`, and `marketplace`
+ Offensive, inappropriate, or non-inclusive words and phrases
