In order to submit a project proposal or access an existing project, you must first log in to CDAS website.
This website is accessible using several different services.
If you already have an account with one of these login services, please click the one you wish to log in with:
- Login.gov - For users who do not have NIH or IMS employee credentials.
-
NIH Login
- An account to log into the NIH network for NIH staff.
eRA Commons users are advised to log in via Login.gov instead. Please see the eRA Commons website for more information about this transition. Please see our Registration page for information about creating a Login.gov account.
-
IMS Login Service
- An account provided by IMS for users who do not have NIH or IMS employee accounts
The IMS Login Service is being retired in May 2025. Users are advised to log in using Login.gov instead, using the same email address that they used for the IMS Login Service. Using the same email will ensure a seamless transition and will not require any additional steps to access all your current projects. Please see our Registration page for information about creating a Login.gov account.
If you do not have credentials at any of these services, you may register for a new account.
