Email verification
Summary: Managed Better Auth email verification confirms that users own the email address they register with, using either a numeric OTP code (works with shared or custom email providers) or a click-through verification link (requires a custom email provider). Both methods expire after 15 minutes and can be resent; verification can be configured as required or optional in the Neon Console, controlling whether unverified users can sign in.
Email verification
Section titled “Email verification”Verify user email addresses during sign-up or account creation
Email verification ensures users own the email addresses they register with. The application name shown in these emails is configurable per branch. See Application name.
Managed Better Auth supports two verification methods:
- Verification codes (users enter a numeric code from their email) - works with shared or custom email providers
- Verification links (users click a link in their email) - requires a custom email provider
Note: Verification links require a custom email provider. If you're using the shared email provider, use verification codes instead.
Enable email verification
Section titled “Enable email verification”Console
In your project's Settings → Auth page, enable Sign-up with Email and Verify at Sign-up. Choose your verification method.
CLI
Enable email and password authentication with verification required using neon neon-auth config email-password update:
neon neon-auth config email-password update --enabled --require-email-verificationAPI
Update the configuration with the Update email and password configuration endpoint. Replace {project_id} and {branch_id} with your project and branch IDs:
curl -X PATCH 'https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth/email_and_password' \
-H 'Authorization: Bearer $NEON_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"enabled": true,
"require_email_verification": true
}'Verification links
Section titled “Verification links”Verification links require a custom email provider. See Email provider configuration to set this up.
When a user clicks the verification link in their email, the Managed Better Auth server handles verification and redirects them back to your application. Your app checks for the new session and shows the appropriate UI.
1. Check session on mount
Section titled “1. Check session on mount”Add a session check when your component mounts to detect when a user returns from clicking the verification link:
import { useEffect, useState } from 'react';import { authClient } from './auth';export default function App() { const [user, setUser] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { authClient.getSession().then(({ data }) => { if (data?.session) { setUser(data.session.user); } setLoading(false); }); }, []);}2. Handle sign-up with verification
Section titled “2. Handle sign-up with verification”After calling signUp.email(), check if verification is required and show a message:
const handleSignUp = async (e) => { e.preventDefault(); setMessage(''); try { const { data, error } = await authClient.signUp.email({ email, password, name: name || email.split('@')[0] || 'User', }); if (error) throw error; // Check if email verification is required if (data?.user && !data.user.emailVerified) { setMessage('Check your email for a verification link!'); } else { setMessage('Account created! Please sign in.'); } } catch (error) { setMessage(error?.message || 'An error occurred'); }};3. Check verification status
Section titled “3. Check verification status”Access the emailVerified field from the user object:
const { data } = await authClient.getSession();if (data?.session?.user && !data.session.user.emailVerified) { // Show verification prompt or restrict features console.log('Please verify your email to continue');}Verification codes
Section titled “Verification codes”If you prefer verification codes, users receive a numeric code via email and enter it in your application. Your app switches between the auth form and a verification form.
1. Add verification state
Section titled “1. Add verification state”Add state to track which form to show:
const [step, setStep] = useState('auth'); // 'auth' or 'verify'
const [code, setCode] = useState('');2. Handle code verification
Section titled “2. Handle code verification”Create a handler for code verification:
const handleVerify = async (e) => { e.preventDefault(); setMessage(''); try { const { data, error } = await authClient.emailOtp.verifyEmail({ email, otp: code, }); if (error) throw error; // Check if auto-sign-in is enabled (default behavior) if (data?.session) { setUser(data.session.user); setStep('auth'); } else { setMessage('Email verified! You can now sign in.'); setStep('auth'); setIsSignUp(false); setCode(''); } } catch (error) { setMessage(error?.message || 'An error occurred'); }};3. Show verification form
Section titled “3. Show verification form”When step is 'verify', show the verification form:
if (step === 'verify') {
return (
<div>
<h1>Verify Your Email</h1>
<p>Enter the code sent to {email}</p>
<form onSubmit={handleVerify}>
<input
type="text"
placeholder="Verification code"
value={code}
onChange={(e) => setCode(e.target.value)}
required
/>
<button type="submit">Verify</button>
</form>
{message && <p>{message}</p>}
</div>
);
}4. Switch to verification after sign-up
Section titled “4. Switch to verification after sign-up”After calling signUp.email(), switch to the verification step:
if (data?.user && !data.user.emailVerified) { setMessage('Check your email for a verification code'); setStep('verify'); // Switch to verification form}Complete example: App.jsx with verification codes
Here's a complete, minimal App.jsx file that includes sign-up, sign-in, and verification code functionality:
import { useState, useEffect } from 'react';
import { authClient } from './auth';
import './App.css';
export default function App() {
const [session, setSession] = useState(null);
const [user, setUser] = useState(null);
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const [loading, setLoading] = useState(true);
const [message, setMessage] = useState('');
const [step, setStep] = useState('auth'); // 'auth' or 'verify'
const [code, setCode] = useState('');
const [isSignUp, setIsSignUp] = useState(true);
useEffect(() => {
authClient.getSession().then((result) => {
if (result.data?.session && result.data?.user) {
setSession(result.data.session);
setUser(result.data.user);
}
setLoading(false);
});
}, []);
const handleSignUp = async (e) => {
e.preventDefault();
setMessage('');
const { data, error } = await authClient.signUp.email({
email,
password,
name: email.split('@')[0] || 'User',
});
if (error) {
setMessage(error.message);
return;
}
if (data?.user && !data.user.emailVerified) {
setMessage('Check your email for a verification code');
setStep('verify'); // Switch to verification form
} else {
const sessionResult = await authClient.getSession();
if (sessionResult.data?.session && sessionResult.data?.user) {
setSession(sessionResult.data.session);
setUser(sessionResult.data.user);
}
}
};
const handleSignIn = async (e) => {
e.preventDefault();
setMessage('');
const { data, error } = await authClient.signIn.email({ email, password });
if (error) {
setMessage(error.message);
return;
}
if (data?.session && data?.user) {
setSession(data.session);
setUser(data.user);
}
};
const handleVerify = async (e) => {
e.preventDefault();
setMessage('');
try {
const { data, error } = await authClient.emailOtp.verifyEmail({
email,
otp: code,
});
if (error) throw error;
if (data?.session) {
setSession(data.session);
setUser(data.session.user);
setStep('auth');
} else {
setMessage('Email verified! You can now sign in.');
setStep('auth');
setIsSignUp(false);
setCode('');
}
} catch (error) {
setMessage(error?.message || 'An error occurred');
}
};
const handleSignOut = async () => {
await authClient.signOut();
setSession(null);
setUser(null);
};
if (loading) return <div>Loading...</div>;
if (session && user) {
return (
<div>
<h1>Logged in as {user.email}</h1>
<button onClick={handleSignOut}>Sign Out</button>
</div>
);
}
if (step === 'verify') {
return (
<div>
{' '}
<h1>Verify Your Email</h1>
<p>Enter the code sent to {email}</p>
<form onSubmit={handleVerify}>
{' '}
<input
type="text"
placeholder="Verification code"
value={code}
onChange={(e) => setCode(e.target.value)}
required
/>{' '}
<button type="submit">Verify</button>
</form>{' '}
{message && <p>{message}</p>}
</div>
);
}
return (
<div>
<h1>{isSignUp ? 'Sign Up' : 'Sign In'}</h1>
{message && <p>{message}</p>}
<form onSubmit={isSignUp ? handleSignUp : handleSignIn}>
<input
type="email"
placeholder="Email"
value={email}
onChange={(e) => setEmail(e.target.value)}
required
/>
<input
type="password"
placeholder="Password"
value={password}
onChange={(e) => setPassword(e.target.value)}
required
/>
<button type="submit">{isSignUp ? 'Sign Up' : 'Sign In'}</button>
</form>
<p>
<button onClick={() => setIsSignUp(!isSignUp)}>
{isSignUp ? 'Already have an account? Sign in' : "Don't have an account? Sign up"}
</button>
</p>
</div>
);
}Resending verification emails
Section titled “Resending verification emails”Both verification links and verification codes expire after 15 minutes. Allow users to request a new one:
const handleResend = async () => { try { const { error } = await authClient.sendVerificationEmail({ email, callbackURL: window.location.origin + '/', }); if (error) throw error; setMessage('Verification email sent! Check your inbox.'); } catch (error) { setMessage(error?.message || 'An error occurred'); }};The server sends whichever type (verification link or verification code) you configured in the Console.
Required vs optional verification
Section titled “Required vs optional verification”When email verification is required in your Console settings, users cannot sign in until they verify. When verification is optional, users can sign in immediately but their emailVerified field remains false until verified.
