Hargreaves Lansdown Login: Step-by-Step Guide (2026)

August 17, 2026 3 Min Read

Hargreaves Lansdown login needs four pieces of information, not just a password. Here’s exactly what to enter, in what order, plus what to do if you’re locked out.

Quick Answer: Hargreaves Lansdown Login

A Hargreaves Lansdown login needs four things: your username, date of birth, Online Password, and three random digits from your six-digit Secure Number. Enter these across a short form on the website. Or use fingerprint sign-in through the mobile app once it’s set up. If any detail is missing, HL’s own reset tools handle recovery — never share these details anywhere else.

1. Hargreaves Lansdown Login on the Website

Step 1: Click “Log in” at the top right of the Hargreaves Lansdown website.
Step 2: Enter your username, the mix of letters and numbers you set when you registered.
Step 3: Provide your date of birth in ddmmyy format, so 1 January 1970 becomes 010170.
Step 4: Select “Continue.” Then enter your Online Password. It needs at least one upper-case letter, one lower-case letter, and often a special character too.
Step 5: Enter the three digits requested from your six-digit Secure Number, then select “Log in.”

2. Hargreaves Lansdown Login on the Mobile App

Getting started: Open the app. Select “Accounts” in the bottom-left corner to reach the login screen.
First-time setup: The app can save your username and date of birth. So you only need your password and Secure Number digits after that.
Fingerprint option: Once set up, a fingerprint or face scan can replace manual entry for most logins.
Why it’s faster: The app remembers more of your details on the device. So day-to-day sign-in takes far fewer taps than the website.

3. What to Do If You’re Locked Out

Forgotten username or password: Use the “reset your login details” tool on the website. It walks through a few identity checks, then a reset.
Lost Secure Number: Support can reissue a new Secure Number once they confirm who you are through standard checks.
Too many failed attempts: Accounts can lock temporarily after repeated wrong entries, so wait and retry rather than guessing repeatedly.
Still stuck: Contact Hargreaves Lansdown directly through their official support channels rather than any third-party site.

4. Login Security Features

Two-step checks: A code sent by SMS or phone call adds a second check beyond your password.
Secure Number: Only three random digits get asked each time. So no single login ever reveals your full six-digit number.
Fingerprint login: A fingerprint or face scan on the app adds a device-level lock beyond your account password.
Session timeouts: Accounts log out on their own after a period of inactivity. This limits exposure on shared devices.
