Aside Password Manager

Password Manager

Aside Password Manager is a native credential manager the agent can use without seeing generated passwords. Use passwordManager in the REPL to autofill logins, payment cards, and identities, create signup password refs, search saved credential sites, and store credentials.

Before using Aside Password Manager as the website login source, check memory/USER.md for connected external password manager preferences. If the user configured one or more external providers, try a connected provider first and use Aside Password Manager to unlock that provider or as the fallback. If no connected external provider preference is present, use Aside Password Manager as the default login/autofill source.

Use Cases

1. Check websites the user is using

When searching for task-relevant information, saved credential sites are useful hints about services the user already uses. It never exposes the secret values so it's safe to use for searching.

const keywords = ['search 1', 'search 2', 'search 3'];
const vaults = await passwordManager.listVaults();
// vaults: [{ vaultId, name }, ...]
const results = await Promise.all(keywords.map(k => passwordManager.listItems({ text: k })));
// results: [[{ title, urls, category, username, oauth, primaryHost, vaultId, itemId }, ...], ...]

Use these results to find relevant sites the user already uses.

2. Autofill a selected item

When you are on a login page, search login candidates with listItems(...), then use autofillItem(page, itemId) only after selecting a clearly matching item. listItems(...) may return multiple candidates. Choose by site, title, username/OAuth account, URLs, and task context. Ask only when the right account is genuinely ambiguous - last resort! If Aside has no usable login, continue normal page inspection. Users may have other password managers (e.g. 1Password), and focusing a field may reveal their autofill UI.

const candidates = await passwordManager.listItems({ text: 'example.com', category: 'login' });
console.log(candidates);

// If one candidate clearly matches the user's task, use it and continue browsing.
await passwordManager.autofillItem(page, '<selected-item-id>');

3. Autofill a payment card or identity on checkout forms

autofillItem also fills credit-card and identity items. On a payment/checkout form, search card items and autofill the matching one instead of asking the user to type card details. It fills card number, holder name, expiry, and CVV across the form (including hosted card-number iframes) without exposing the values to you.

const cards = await passwordManager.listItems({ category: 'credit-card' });
console.log(cards);

// Make sure the card form is visible (e.g. the "credit card" payment method is selected), then:
await passwordManager.autofillItem(page, '<selected-card-item-id>');
// Verify from a fresh snapshot that the visible card fields are filled. Never print card values.

Billing name/address fields are not card data; fill them from a matching identity item or the user's known profile.

4. Sign up

If signup is needed to complete the task, save the new credential in Aside vault unless the user explicitly says not to. For email or username, prefer a common ID / email that the user uses from the user's existing items. For password: never create or inspect the password yourself. Use generatePassword(...), which returns only a GeneratedPasswordRef. Pass only constraints the site explicitly requires.

const passwordRef = await passwordManager.generatePassword({
  length: 12,
  include: ['lowercase', 'uppercase', 'digit', 'symbol'],
  symbols: '!@#$%^&*',
});

Pass the reference into the page field. Use a field ref from the latest snapshot.

await passwordManager.fillPassword(page, 'e32', passwordRef);
// proceed to sign up...

After signup completes, YOU SHOULD save the credential, unless it would be lost. Before creating a new item, call listVaults(). Choose a vault from a matching existing item, a clearly relevant vault name, or other task context. If there is no better signal, use the first vault.

const vaults = await passwordManager.listVaults();
await passwordManager.createItem({
  vaultId: vaults[0].vaultId,
  category: 'login',
  title: '<human-readable title>',
  urls: ['<page URL>'],
  notes: '<context>',
  fields: [
    { label: 'username', value: username, designation: 'username' },
    { label: 'password', value: passwordRef, designation: 'password', isSecret: true },
  ],
});

For reset-password or change-password flows, do not create a duplicate item when the existing item is clear from search results or task context. After the password change succeeds, update the existing item:

await passwordManager.updateItem(itemId, {
  fields: [
    { label: 'password', value: passwordRef, designation: 'password', isSecret: true },
  ],
});

5. Save credentials

If a website shows a one-time secret, API key, token, SSH key, recovery code, or similar credential that the user may need later, save it in Aside password manager. Before saving, call listVaults() and choose the most context-appropriate vault. If none is obvious, use the first vault.

const secret = await page.locator('<refId>').textContent();
const vaults = await passwordManager.listVaults();
await passwordManager.createItem({
  vaultId: vaults[0].vaultId,
  category: 'api-credential',
  title: '<human-readable title>',
  notes: '<context>',
  urls: ['<page URL>'],
  fields: [
    { label: 'secret', value: secret, isSecret: true },
  ],
});

Use isSecret: true for values that should be stored as secret/guarded fields. Use a specific category when it is obvious, such as api-credential or ssh-key. Use secure-note when the credential does not fit a structured category.
