Short answer: not directly. In Prefect Cloud 3.x, blocks (including Secret blocks) are scoped to a workspace and cannot be shared across workspaces. You’ll need to recreate them in your dev workspace. Recommended approaches: - Preferred: Source secrets from your secret manager (AWS Secrets Manager, Vault, etc.) and “seed” both workspaces from that source of truth. - One‑off copy: Use a small script to read secrets from prod and write them to dev. Secret values are encrypted at rest but can be retrieved in code with

.get()

when you have access. Example copy script (handle carefully; don’t log secrets):

from prefect.blocks.system import Secret
from prefect.settings import temporary_settings, PREFECT_API_URL, PREFECT_API_KEY

# Fill in your API URLs/keys for each workspace
PROD = {
    PREFECT_API_URL: "<https://api.prefect.cloud/api/accounts/<account_id>/workspaces/<prod_workspace_id>>",
    PREFECT_API_KEY: "<prod_api_key>",
}
DEV = {
    PREFECT_API_URL: "<https://api.prefect.cloud/api/accounts/<account_id>/workspaces/<dev_workspace_id>>",
    PREFECT_API_KEY: "<dev_api_key>",
}

# List the secret block names you want to copy
secret_names = ["db-password", "slack-token"]

# Read from prod
with temporary_settings(PROD):
    values = {name: Secret.load(name).get() for name in secret_names}

# Write to dev (creates or updates)
with temporary_settings(DEV):
    for name, value in values.items():
        Secret(value=value).save(name, overwrite=True)

Helpful tips: - You can list what blocks exist in a workspace with:

prefect block ls

- Inspect an individual block (metadata only; not the secret value):

prefect block inspect -n <block-name>

- Keep block names consistent across environments so your code can always

Secret.load("<name>")
