To log in to Mr Green, open the website or the iPhone or Android app and sign in with the email or username and password you registered with. The steps above show the order, and this page covers what sits behind them and what to try when a login fails.
Before you start, have your login details to hand: the email address or username on your account and your password. If you have not registered yet, the sign-up guide comes first, because there is nothing to log in to without an account. Keep your identity documents within reach as well, since Mr Green requires verification.
Logging in happens only on Mr Green's own website or app. This page has no login form and will never ask for your password. To reach the casino, use visit Mr Green or open the app you already have installed.
What happens when you log in
A login is a simple match: the details you enter are compared with the details you set when you registered. That makes the small things matter. Whether you registered with an email address or a username, enter the same one each time. Passwords are case sensitive, and a stray space copied from a note or message is enough to make a correct password fail.
Website or app
Mr Green works in three places: the website on desktop and mobile, the iPhone app and the Android app. The credentials you use are the same wherever you sign in. The website needs nothing installed, which suits you if you only play now and then or use a shared computer. An app suits you if you want to open Mr Green from your phone's home screen.
If you want to compare the options, the mobile version guide covers the browser on a phone, and there are separate pages for the iPhone app, the Android app and the general app overview. Download an app only from the app store for your phone, and open the website only by typing the address yourself, using a bookmark you made on the real site, or following visit Mr Green.
Identity and age checks
Mr Green requires identity verification. A UK-licensed operator must confirm your age and identity before you can deposit or play, so the documents you submit have to match the details you registered with. If you gave a nickname instead of your full legal name, or a different date of birth by mistake, the check can stall. The verification guide lists what to prepare and how the process works.
The practical points are straightforward:
- Use the legal name and date of birth you registered with, as they appear on your documents.
- Make sure the document images are clear, complete and uncropped, with all four corners visible.
- Use documents that are current and in your own name, never someone else's.
- Keep the email address and phone number on your account up to date, since that is how you stay in reach.
Verification can take time, because a person or a system has to review what you send. Do not leave it until you want to cash out. Completing it early means one less thing to deal with later. Whether a check is still open on your account is something you see after you log in on Mr Green's own site or app, not here.
Checking you are on the right site
Mr Green holds a UK licence, and you can look up a UK operator on the Gambling Commission public register. If you want to know more about how safe the casino is, the safety review and the legitimacy review go through it.
Fake pages that copy a casino's look exist, and they exist to collect passwords. The surest defence is to start from a place you trust: your own bookmark, the app you installed from the store, or the link on this page. A page you reach from an unexpected message, a social media post or a search advertisement you do not recognise deserves suspicion before you type anything into it.
What you can do after logging in
Once you are signed in, you can reach the parts of the casino that need an account, such as the games, deposits and withdrawals. If you came here only for the login, you can stop at the steps above. The sections below are for when something goes wrong.

If you cannot log in
Most failed logins have a simple cause. Work through the list in order, because the first few fixes take seconds.
Check the basics
Look at what you typed. Check whether Caps Lock is on, whether the keyboard has switched to another language, and whether your device has autofilled an old password or a different email address from a previous account. If the field shows dots, use the option to reveal what you typed, or type the password again slowly.
Then think about which sign-in detail you used when you registered. People often have several email addresses and sometimes a username as well. If the first does not work, try the others you may have used.
Forgotten password
Use the password reset option on the Mr Green login screen, on the website or in the app, and follow it through to the end. Reset your password only through the screen on Mr Green's own site or app. Do not reset it through a link on another website, in a message from someone else, or in an advertisement.
When you choose a new password, make it one you have not used elsewhere. If you use a password manager, update the saved entry straight away. Otherwise your device may keep offering the old password and you will find yourself locked out again by your own autofill.
The website will not load or looks wrong
Try the simple fixes first. Reload the page, check your connection, and switch between Wi-Fi and mobile data. If the page still fails, try another browser, or close the tab and reopen the site. Clearing the saved data for the site in your browser sometimes helps when an old session is confusing the page.
If the address looks wrong or the page asks for details that seem out of place, close it. Go back to a bookmark or visit Mr Green from this page and try again.
The app will not open or sign you in
Make sure the app is up to date, since an old version can stop working properly. Restart your phone and open the app again. If that does not help, delete the app and install it again from the app store for your phone, then sign in with the same details as before. The iPhone app page and the Android app page have more on each version.
If the app misbehaves but the website works, you can sign in on the website in the meantime. The credentials are the same.
Verification is holding things up
Sometimes the problem is not the login but a verification step that is not finished. If you have been asked for documents, send clear, complete copies in the name you registered with, and follow the verification guide. A rejected document usually has a simple cause: a blurry image, a cut-off corner, an expired document, or a name that does not match the account. Fix that one thing and send it again rather than trying a different type of document each time.
When to contact support
If the reset does not work, you are sure your details are right and you still cannot sign in, or you suspect someone else has used your account, contact Mr Green support. The contact page shows how to reach them.
It helps to give your username or the email address on the account, a short description of what happens when you try to sign in, and which device and browser or app you are using. Never include your password in a message to anyone, support included. Real support staff have no need for it.
If you notice activity on your account that you do not recognise, contact support promptly and change your password. If the same password was used on another site, change it there too.
Keeping your account secure and under control
Enter your password only on Mr Green's own website or app. This site never asks for it, and neither should a message, a pop-up or a page you reached from an advertisement. If you are unsure, close the page and start again from your bookmark or the app.
Use a password you use nowhere else. A long, unique password is much harder to guess or to reuse if another site is breached. A password manager makes that practical, because you only need to remember one master password.
Keep your devices tidy. Lock your phone with a PIN, fingerprint or face unlock, and keep the operating system and the app updated. On a shared or public computer, log out when you finish and do not let the browser save the password.
Do not share your login. Playing from someone else's account, or letting someone use yours, creates problems for both of you. If more than one person uses your device, a separate user profile on the device keeps your saved details apart.
Keep your documents ready. Since Mr Green requires verification, having a current photo ID and proof of address to hand makes the check quicker when you are asked. Make sure the names on them match your account.
Use the tools for control. Logging in is the point where you decide how much time and money you want to spend. Mr Green offers deposit limits and time-outs, and GAMSTOP covers it if you want to self-exclude from all UK-licensed sites; the safer gambling page explains the tools, and GamCare runs the National Gambling Helpline if you want to talk to someone. Setting a deposit limit before you play is easier than doing it after a session has gone on.
Gambling is paid entertainment, not a way to make money, so keep it to money you can spare.
