Hi there thanks for posting in the community! Keeping customer data secure is a primary objective at Lucid. When working in Lucidscale Cross-Account roles are the preferred method from AWS for granting 3rd party access to your account. This method allows Lucidscale to securely store credentials that allow you to easily refresh your diagram. See these AWS resources for more information:

• How to Use an External ID when Granting Access to Your AWS Resources to a Third Party


• Providing Access to AWS Accounts Owned by Third Parties

Lucidscale also utilizes the following practices:

• enforced unique External IDs


• CLI script alternative


• industry standard safe document storage

For complete security information please take a look at our Import and Manage AWS Infrastructure Data article and the Credential Usage Management and Security article from the Lucidscale Help Center and post any additional questions below.
