How do I change my username, photo or details?
Updated October 24, 2026
Your profile details
In Account settings > Profile you edit your first and last name (up to 100 characters each), your bio (up to 500), your location (up to 80, shown on your public profile) and your photo. Save changes stays disabled until you change something.
Phone, country and email are read-only, each with a line explaining why. There is no button on that screen to change them.
The photo
JPG or PNG, at least 400 x 400 px and 10 MB at most. The dialog shows the image size before saving.
Your username
Your public profile lives at /collection/{username}. The Change button opens the username change, with a confirmation that states the consequence: your old link /collection/{previous} stops working and there is no redirect.
The username must be 3 to 30 characters, with lowercase letters, numbers and single underscores. Reserved words are refused and availability is checked as you type.
The first change is immediate. After a change, the next one opens 30 days later and the button stays off until then, with the date shown. A username someone gives up is held for 45 days: nobody else can take it and the previous owner can reclaim it.
What people see
Your public profile shows your photo, name or username, bio and location, plus your rating, sales, followers and the tabs for items for sale, collection and reviews. Items that are not for sale stay in your collection with the price hidden.
