A $ChimeSign is like a username for Chime members. You can share your $ChimeSign with other members to send and request money with Pay Anyone.
To change your $ChimeSign, open the Chime app and go to Profile > Personal info. You can change your $ChimeSign up to three times total.
If you’d like to hide your $ChimeSign from other members, you can do that in the Privacy settings of your Chime app.
