+AWS SSO requires a `~/.aws/config` file on the host with your SSO session configuration. If you already have this on another machine, copy it:

+```bash
+scp -r user@other-machine:~/.aws ~/.aws

+
+Or configure from scratch:
+
+```bash
+aws configure sso
+```
+
+You'll be prompted for:
+- SSO session name
+- SSO start URL
+- SSO region
+- Registration scopes (typically `sso:account:access`)
+
+The `~/.aws` directory must be mounted into the container (see docker-compose example below).

 ### Key points
 
 - **Project files** (`/workspace`) are always safe — they're your host filesystem.
 - **opencode config** is auto-generated from `OPENCODE_PROVIDER` env var on each start. It only sets provider and model — no MCP servers. To persist MCP server config, mount your own config file (see Custom opencode Config below).
 - **opencode data** (session history, memory) is lost with `--rm` unless you add a named volume.
-- **AWS SSO tokens** are stored inside the container and lost on restart. Re-run `aws sso login` after restarting.
+- **AWS SSO tokens** persist across restarts when `~/.aws` is mounted (recommended for Bedrock users).

-### Persisting opencode data

-Add a named volume to keep session history and memory between runs:
