Get your Hetzner Object Storage access keys

- 2
Open "Object Storage" in the sidebar and create a bucket in fsn1, nbg1 or hel1 if you don’t have one.
- 3
Go to "Manage credentials" and generate a new access key / secret key pair.
- 4
In Universal S3 Client, add Hetzner, pick the same location as your bucket and paste the keys.

good to know
Before you connect
Buckets live in one of three EU locations only (fsn1, nbg1, hel1) — the endpoint is location-specific, so pick the location that matches your bucket.
Hetzner enforces newer S3 checksum behavior inconsistently; Universal S3 Client pins an SDK version that is verified to work with Hetzner uploads.

faq
Hetzner Object Storage — frequently asked
+ Does Universal S3 Client work with Hetzner Object Storage?
Yes — Hetzner is a first-class preset. Pick your location (fsn1, nbg1 or hel1), paste your access keys, and the app builds the https://{location}.your-objectstorage.com endpoint for you.
+ Is there a Hetzner Object Storage app for iPhone?
Universal S3 Client is a free iPhone, iPad and Mac app that manages Hetzner buckets: browse folders, upload with progress, preview JSON/YAML/CSV files and share presigned links.
+ Why do some S3 tools fail to upload to Hetzner?
Newer AWS SDKs enforce payload checksums that Hetzner’s implementation rejects. This app ships with an SDK version tested against Hetzner, so uploads work out of the box.
+ Is Hetzner Object Storage GDPR-friendly?
Data stays in German or Finnish data centers under EU jurisdiction, which makes Hetzner a common choice for GDPR-sensitive workloads.
