Username allocation is on a first-come first-served basis. If a username that you want is already taken we suggest that you try using underscores or numbers to create a variation. Some members of our community use Unsplash to create private collections of photos, so while an account may seem dormant, it can be active.
You’ll be prompted to set a username when joining Unsplash.
When you set a username:
Ensure you add no spaces
Use only English characters
Use only lowercase letters
Use only letters, numbers and underscores
Alternatively if you prefer, you can login in using the Facebook option.
