Add Content Credentials in Lightroom on mobile (iOS)

Open a photo in Lightroom on mobile and make relevant edits. 

To attach Content Credentials, select the Share   and select Export as....

Allow the Content Credentials toggle to apply them to your photos, and then select the Settings option to open the Content Credentials dialog box. 

Select the Information to include:

• Producer: The name listed on your Adobe account.
• Connected accounts: Select your preferred social media account. You can connect your Behance, Instagram, or any other social media account by selecting Connect accounts.
• Edits and activity: The editing and processing actions taken to produce the final image.

Select the Store in option:

• Content Credentials cloud: This lets you publish the information on a public Content Credentials cloud separate from the cloud file storage included in your Adobe plan. This option makes Content Credentials persistent and recoverable. It keeps files smaller but less private since Content Credentials published to the cloud may appear in results when people search for content that matches or closely resembles your own. 
  
• Files: This embeds the information in the exported file.
• Files and cloud: This gives you the benefit of both the methods mentioned earlier.

Add all the other fields and then select  . 

Select the More   and select App settings > Content Credentials > Connect accounts.

Sign in with the same account used to log into Lightroom for mobile (iOS).

Connect your third party and social media to ensure the information on the connected accounts' pages is included in the final signed asset.
