On the s3cmd page (https://docs.digitalocean.com/products/spaces/reference/s3cmd/), there are two places where it says you can generate access keys by visiting the API page (https://cloud.digitalocean.com/account/api/tokens?i=fe6032). But in the Access Keys documentation (https://docs.digitalocean.com/products/spaces/how-to/manage-access/#access-keys), it says instead to visit the Spaces Access Keys page (https://cloud.digitalocean.com/spaces/access_keys).
I might just not have the right permissions, but when I visit the API page, it doesn't mention Access Keys at all. So I feel like maybe the s3cmd page should instead link to the Access Keys page? Not sure, but figured it was worth reporting.
