When you verify your device with a One-Time Password (OTP), our system is designed to remember you and keep you logged in safely for a few months.
If you are being asked to enter a new code every single time you log in, it usually just means your web browser is erasing the little digital memory card (called a "cookie") that tells us your device is safe and verified.
Before we look at your settings, let’s rule out a simple mismatch with these checks:
Check 1: Make sure you are not using Private or Incognito mode
Incognito or private browsers will be labeled with Incognito, Private browsing or InPrivate on the top right of the window or on the browser
Are you using a private/incognito browser?
Private or incognito browsing windows are built to forget everything the moment you close them. While they are great for privacy, they also throw away the secure 'handshake' that tells NightsBridge your computer is verified.
The Fix: Close any private browsing windows and open a normal browser window before logging into your NightsBridge home.
Check 2: The "Same Device, Same Browser" check
To keep your calendar secure while saving you time, NightsBridge is designed to remember the exact browser on the exact device you are using.
Because devices and browsers don't share memory with each other:
- If you switch devices: If you verified your phone yesterday but are logging in on your laptop today, the system will treat your laptop as a brand-new visitor.
- If you switch browsers: If you usually use Chrome but opened Safari today, the browser memory won't transfer over.
Are you using the same browser on the same device each time you log in?
Step 3: Make sure your browser is allowed to remember us (Cookies)
Let's help you check your browser settings.
In case you're unsure, you can check which browser you're using by looking at the browser icon:
Which Browser are you using?
- Click the three vertical dots in the top-right corner
- and select Settings.
Click Privacy and security in the left-hand menu.
Click Site settings.
Scroll down and click Additional content settings (if displayed).
Click On-device site data.
Check whether "Allow sites to save data on your device" is turned On.
If the setting isn't there
Some versions of Chrome display this option under:
Settings → Privacy and security → Third-party cookies
If you see "Delete site data when you close all windows", ensure it is turned off.
- Click the ⋯ (three dots) in the top-right corner.
- Select Settings.
In the left-hand menu, click Privacy, search, and services.
Click on the Clear browsing data section.
Click Choose what to clear every time you close the browser.
Look for the Cookies and other site data option.
- Make sure this is Off so that Edge will keep cookies between sessions, allowing websites to remember trusted devices and login preferences.
Additional check (optional)
While you're in Privacy, search, and services, it's also worth checking that Tracking prevention is not configured with settings or extensions that aggressively remove cookies. In most cases, the default Balanced setting works well and does not interfere with normal website logins.
Important: If Microsoft Edge is configured to delete cookies when it closes, the browser won't remember that you've already completed OTP verification. Even if your OTP is valid for 90 days, you may be prompted to enter a new OTP every time you sign in after closing the browser.
- Click the ☰ (three horizontal lines) in the top-right corner.
- Select Settings.
Click Privacy & Security in the left-hand menu.
Scroll down to the Browsing Data section.
Check that your Clear cookies and site data when Firefox is closed is disabled.
- With this setting Off, Firefox will keep cookies between sessions, allowing websites to remember trusted devices and login preferences.
Additional check (optional)
While still on the Privacy & Security page, scroll to the History section.
If you have customised history settings, click on Choose what you want Firefox to remember.
Make sure that the option to Clear history when Firefox closes is not selected.
Important: If Firefox is configured to delete cookies when it closes, the browser won't remember that you've already completed OTP verification. Even if your OTP is valid for 90 days, you may be prompted to enter a new OTP each time you sign in after closing the browser.
- In the menu bar, click Safari
- Select Settings (or Preferences on older versions of macOS).
- Click the Privacy tab
- Review this setting:
- Prevent cross-site tracking
- This setting can remain On. It is designed to reduce cross-site tracking and generally does not interfere with normal website logins or trusted device recognition.
- Prevent cross-site tracking
- Now select Advanced Settings.
Review this setting:
- Block all cookies
- Make sure this setting is Off so websites can store cookies to remember your login and trusted device.
Important: Safari does not normally delete cookies when it closes. However, if Block all cookies is enabled or you're using Private Browsing, Safari may not remember that you've already completed OTP verification. This can result in you being asked to enter a new OTP each time you sign in, even if the verification period is set to last 90 days.
Were your browser settings correct?
If the issue doesn't lie with your browser settings, here are two addition checks to cover:
Check 3: Check your security software or extensions
Sometimes, helpful internet security software, antivirus programs, or privacy extensions can be a bit overprotective. They can quietly go behind your browser and sweep away your saved cookies every time you close your window.
Are you using security software like and antivirus?
The Fix: If you use cleaning utilities or internet security software, check their settings to see if they are automatically clearing browser cookies when your browser closes.
Check 4: Are your computer settings managed by your company?
If you use a work computer, your organisation might have automated safety policies in place that delete cookies, force private browsing, or reset browser settings every evening.
Is your computer managed by an IT department?
The Fix: If this applies to you, a quick chat with your IT department will help get NightsBridge added as an exception so your computer can remember your device.
Still being asked for an OTP?
If you have checked all of these settings and you are still being asked for an OTP every time you sign in, please reach out to us! To help us get this sorted for you as quickly as possible, it would be great if you could let our support team know:
- Which web browser you are using (like Safari, Chrome, Edge, or Firefox).
- Whether you are using a work computer or a personal one.
- If this is happening on more than one device.
Update your browser settings as recommended before testing your OTP login again.
Test it!
Now that you've checked and updated your browser settings, log into NightsBridge and process the OTP login.
Close the browser and reopen it again. Log in and check that you're not required to process an OTP to login this time.
Did this solve it?
Great! Glad we could resolve this together.
There are two more checks you're able to do before asking us for help.

Once you've entered your OTP, that specific browser on your device will remember you for a few months so you can skip the extra step. But if you switch to a different browser or log in from a new device, we'll just need to send you a quick OTP to make sure it's really you.
The Fix: Access NightsBridge from a browser and device that has already been verified or process an OTP login to verify your current browser and device.
