## ⚙️ AWS Configuration

### SSO Session Configuration

`~/.aws/config`:

```ini
[sso-session my-company]
sso_start_url = https://my-company.awsapps.com/start
sso_region = us-east-1
sso_registration_scopes = sso:account:access

[profile production-admin]
sso_session = my-company
sso_account_id = 111111111111
sso_role_name = AdministratorAccess
region = us-east-1
output = json

[profile staging-developer]
sso_session = my-company
sso_account_id = 222222222222
sso_role_name = DeveloperAccess
region = us-west-2
output = json
```

### Assume Role Configuration

```ini
[profile base]
region = us-east-1

[profile cross-account-admin]
source_profile = base
role_arn = arn:aws:iam::333333333333:role/AdminRole
region = us-east-1
```

### Legacy SSO (without sso-session)

```ini
[profile legacy-sso]
sso_start_url = https://my-company.awsapps.com/start
sso_region = us-east-1
sso_account_id = 444444444444
sso_role_name = ViewOnlyAccess
region = us-east-1
```

## 🐛 Troubleshooting

<details>
<summary><strong>AWS CLI Not Found</strong> - <code>E_NO_AWS: AWS CLI v2 not detected</code></summary>

<br>

**Solution:** Install AWS CLI v2 following the [official guide](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html)

Verify installation:
```bash
aws --version  # Should show "aws-cli/2.x.x ..."
```

</details>

<details>
<summary><strong>No Profiles Available</strong> - <code>E_NO_PROFILES: No profiles detected</code></summary>

<br>

**Solution:** Configure at least one profile:
```bash
# For SSO
aws configure sso-session

# For legacy SSO
aws configure sso

# For static credentials
aws configure
```

</details>

<details>
<summary><strong>SSO Login Fails</strong> - <code>E_LOGIN_FAIL: SSO login failed</code></summary>

<br>

**Possible causes:**
- Network connectivity issues
- Invalid SSO start URL
- MFA/2FA not completed
- Browser not opening (check firewall/permissions)

**Solution:**
```bash
# Try manual login first
aws sso login --profile your-profile-name

# Check browser permissions
# Ensure port 8080-8090 range is available for OAuth callback
```

</details>

<details>
<summary><strong>Identity Check Fails</strong> - <code>E_STS_FAIL: Unable to fetch identity</code></summary>

<br>

**Possible causes:**
- Credentials expired (SSO token or assume-role session)
- Invalid profile configuration
- Network/VPC issues
- Missing IAM permissions

**Solution:**
```bash
# Force re-authentication
# Press 'l' in awsui to trigger SSO login

# Verify profile configuration
cat ~/.aws/config

# Test manually
aws sts get-caller-identity --profile your-profile-name
```

</details>

<details>
<summary><strong>Amazon Q Not Available</strong> - <code>Amazon Q CLI not available</code></summary>

<br>

**Solution:** Install Amazon Q Developer CLI:
```bash
# macOS
brew install amazon-q

# Other platforms: follow official guide
# https://docs.aws.amazon.com/amazonq/latest/qdeveloper-ug/command-line-installing.html
```

Verify installation:
```bash
q --version
```

</details>

## 🔒 Security

awsui follows AWS security best practices:

- ✅ **Credential Handling**: Only uses AWS CLI's credential system - no credential storage or caching
- ✅ **Temporary Credentials**: Leverages AWS STS and SSO for short-lived tokens
- ✅ **Read-Only Config**: Only reads `~/.aws/config` and `~/.aws/credentials` - never writes
- ✅ **Log Safety**: Sensitive data (tokens, secrets) automatically masked in logs
- ✅ **Environment Isolation**: Supports `AWS_CONFIG_FILE` and `AWS_SHARED_CREDENTIALS_FILE` for custom config locations
- ✅ **No Network Calls**: All AWS operations delegated to official AWS CLI
- ✅ **Subprocess Safety**: Secure subprocess execution with proper escaping

## 🎯 Performance

Target metrics:

- **Startup time**: ≤ 300ms (cold start)
- **Search response**: ≤ 50ms (keystroke to UI update)
- **Profile switch**: ≤ 5s (including SSO login if needed)
