What it does

Email And Password Best Practices is an agent skill from ever-works/ever-works. Configure email verification, implement password reset flows, set password policies, and customise hashing algorithms for Better Auth email/password authentication. Use when users need to set up login, sign-in, sign-up, credential authentication, or password security with Better Auth.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Authentication. It works with Better Auth. The repository describes itself as: Ever® Works™ - The Workshop for AI. An open agentic runtime that autonomously researches, ships, and maintains entire businesses, 24/7 - https://ever.works. The licence is AGPL-3.0.

When your agent uses it

  • Users need to set up login
  • Credential authentication
  • Password security with Better Auth

Example prompts

  • “/email-and-password-best-practices”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Enable email/password: emailAndPassword: { enabled: true }
  2. Configure emailVerification.sendVerificationEmail
  3. Add sendResetPassword for password reset flows
  4. Run npx @better-auth/cli@latest migrate
  5. Verify: attempt sign-up and confirm verification email triggers

What it can do on your machine

Read from SKILL.md and the folder at commit 330f7b9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Email And Password Best Practices loads about 1.5k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 338 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Configure email verification, implement password reset flows, set password policies, and customise hashing algorithms for Better Auth email/password authentication. Use when users need to set up login, sign-in, sign-up, credential authentication, or password security with Better Auth.

Quick Start

  1. Enable email/password: emailAndPassword: { enabled: true }
  2. Configure emailVerification.sendVerificationEmail
  3. Add sendResetPassword for password reset flows
  4. Run npx @better-auth/cli@latest migrate
  5. Verify: attempt sign-up and confirm verification email triggers

Email Verification Setup

Configure emailVerification.sendVerificationEmail to verify user email addresses.

ts
import { betterAuth } from 'better-auth';
import { sendEmail } from './email'; // your email sending function

export const auth = betterAuth({
	emailVerification: {
		sendVerificationEmail: async ({ user, url, token }, request) => {
			await sendEmail({
				to: user.email,
				subject: 'Verify your email address',
				text: `Click the link to verify your email: ${url}`
			});
		}
	}
});

Note: The url parameter contains the full verification link. The token is available if you need to build a custom verification URL.

Requiring Email Verification

For stricter security, enable emailAndPassword.requireEmailVerification to block sign-in until the user verifies their email. When enabled, unverified users will receive a new verification email on each sign-in attempt.

ts
export const auth = betterAuth({
	emailAndPassword: {
		requireEmailVerification: true
	}
});

Note: This requires sendVerificationEmail to be configured and only applies to email/password sign-ins.

Client Side Validation

Implement client-side validation for immediate user feedback and reduced server load.

Callback URLs

Always use absolute URLs (including the origin) for callback URLs in sign-up and sign-in requests. This prevents Better Auth from needing to infer the origin, which can cause issues when your backend and frontend are on different domains.

ts
const { data, error } = await authClient.signUp.email({
	callbackURL: 'https://example.com/callback' // absolute URL with origin
});

Password Reset Flows

Provide sendResetPassword in the email and password config to enable password resets.

ts
import { betterAuth } from 'better-auth';
import { sendEmail } from './email'; // your email sending function

export const auth = betterAuth({
	emailAndPassword: {
		enabled: true,
		// Custom email sending function to send reset-password email
		sendResetPassword: async ({ user, url, token }, request) => {
			void sendEmail({
				to: user.email,
				subject: 'Reset your password',
				text: `Click the link to reset your password: ${url}`
			});
		},
		// Optional event hook
		onPasswordReset: async ({ user }, request) => {
			// your logic here
			console.log(`Password for user ${user.email} has been reset.`);
		}
	}
});
Security Considerations

Built-in protections: background email sending (timing attack prevention), dummy operations on invalid requests, constant response messages regardless of user existence.

On serverless platforms, configure a background task handler:

ts
export const auth = betterAuth({
	advanced: {
		backgroundTasks: {
			handler: (promise) => {
				// Use platform-specific methods like waitUntil
				waitUntil(promise);
			}
		}
	}
});
Token Security

Tokens expire after 1 hour by default. Configure with resetPasswordTokenExpiresIn (in seconds):

ts
export const auth = betterAuth({
	emailAndPassword: {
		enabled: true,
		resetPasswordTokenExpiresIn: 60 * 30 // 30 minutes
	}
});

Tokens are single-use — deleted immediately after successful reset.

Session Revocation

Enable revokeSessionsOnPasswordReset to invalidate all existing sessions on password reset:

ts
export const auth = betterAuth({
	emailAndPassword: {
		enabled: true,
		revokeSessionsOnPasswordReset: true
	}
});
Password Requirements

Password length limits (configurable):

ts
export const auth = betterAuth({
	emailAndPassword: {
		enabled: true,
		minPasswordLength: 12,
		maxPasswordLength: 256
	}
});
Sending the Password Reset

Call requestPasswordReset to send the reset link. Triggers the sendResetPassword function from your config.

ts
const data = await auth.api.requestPasswordReset({
	body: {
		email: 'john.doe@example.com', // required
		redirectTo: 'https://example.com/reset-password'
	}
});

Or authClient:

ts
const { data, error } = await authClient.requestPasswordReset({
	email: 'john.doe@example.com', // required
	redirectTo: 'https://example.com/reset-password'
});

Note: While the email is required, we also recommend configuring the redirectTo for a smoother user experience.

Password Hashing

Default: scrypt (Node.js native, no external dependencies).

Custom Hashing Algorithm

To use Argon2id or another algorithm, provide custom hash and verify functions:

ts
import { betterAuth } from 'better-auth';
import { hash, verify, type Options } from '@node-rs/argon2';

const argon2Options: Options = {
	memoryCost: 65536, // 64 MiB
	timeCost: 3, // 3 iterations
	parallelism: 4, // 4 parallel lanes
	outputLen: 32, // 32 byte output
	algorithm: 2 // Argon2id variant
};

export const auth = betterAuth({
	emailAndPassword: {
		enabled: true,
		password: {
			hash: (password) => hash(password, argon2Options),
			verify: ({ password, hash: storedHash }) => verify(storedHash, password, argon2Options)
		}
	}
});

Note: If you switch hashing algorithms on an existing system, users with passwords hashed using the old algorithm won't be able to sign in. Plan a migration strategy if needed.
