If you use tens of passwords every day and you want to get rid of all this hassle, install a password manager and let it take care of all your passwords. LastPass is one such example. Install it on your computer or smartphone, and the tool will automatically save and manage your login information. But there are moments when the Autofill option doesn’t work. In this guide, we’ll take a closer look at this matter and guide you through the troubleshooting process.
Why Is My LastPass Not Auto Filling?
By design, Autofill via LastPass doesn’t work on HTTP webpages for obvious security reasons. If the website you’re visiting is not secure, LastPass won’t trigger the autofill function. But you can always manually enter the login data on HTTP webpages.
It is also worth mentioning that LastPass does not support Flash-based or Silverlight-based websites. If the webpage you’re visiting is built on either of these platforms, autofill won’t work.
Another reason why LastPass autofill won’t work is that you’re using an outdated app or extension version. Install the latest LastPass version and check the results.
Fix LastPass Autofill Not Working on Windows 10 and Mac
Check Autofill Settings
First of all, make sure you enabled the autofill option. Maybe you accidentally disabled it.
- Click the Extensions icon in your browser.
- Locate LastPass, click on More, and select Options.
- Then navigate to Preferences.
- Select General and turn on the Automatically fill login information option. Apply the changes.
- Next, navigate to Account Options and select Extension Preferences.
- Make sure to enable Automatically fill login information. Save the changes and check the results.
Check Never URLs Settings
LastPass has a nifty feature called Never URLs that allows you to disable the password manager for specific websites. If the tool is not auto-filling your login information for specific websites, remove the webpages from the Never URLs list.
Disable Browser Extensions
If you use any browser extensions, some might interfere with LastPass blocking the tool’s autofill feature. Adblockers and privacy extensions are known to block the scripts of the websites you’re visiting, as well as interfere with other extensions. One quick way to test this hypothesis is to disable all your extensions and check if the autofill option works.
If you use Google Chrome or another Chromium-based browser, click the menu and go to More tools. Then select Extensions and switch all of them off.
If you use Safari, navigate to Preferences, click Extensions and untick the checkboxes corresponding to your extensions.
Turn off Browser Password Autofill
If your browser’s autofill feature is enabled, it could block LastPass from auto-filling your login information. So, disable this option and check the results.
- Launch Chrome, and go to Settings.
- Then click on Autofill and select Passwords.
- Toggle off Offer to save passwords and Auto Sign-in.
- Restart your browser, launch LastPass and check if you notice any improvements.
On Safari, navigate to Preferences, select AutoFill, and go to AutoFill settings. Disable all four options and check the results.
If nothing worked, maybe your password manager got corrupted. Reinstalling the tool may help fix the autofill problem. But before you do that, make sure you have access to the master password.
On Windows 10, go to Apps and Features, select LastPass, and hit the Uninstall button.
On macOS, launch Finder, locate and select LastPass and move it to Trash. Restart your computer and reinstall LastPass.
Fix LastPass Autofill Not Working on Android and iOS
If the password manager doesn’t work on your mobile device, use the solutions below.
- Enable Airplane mode and restart your device. This action will refresh your network connection.
- Disable battery optimization for LastPass. Or, better yet, disable your battery saver.
- Clear the cache. On Android, navigate to Settings, select Apps, and tap LastPass. Then select Storage and hit the clear cache button. On iOS, go to Settings, select LastPass and switch on Reset cache on the next launch.
- Update your LastPass app. If you’re running outdated app versions, certain features, such as the autofill option, may not be available.
- Reinstall LastPass. If nothing worked, uninstall and reinstall the app.
To sum up, there are two main reasons why LastPass fails to autofill your login information: either the feature is disabled, or something’s blocking it. To troubleshoot the problem, check your account settings. You can also update the app, and disable your extensions.
Additionally, disabling your browser’s autofill feature may help as well. Did these solutions help you fix the problem? We’re really curious to learn which method worked for you. Let us know in the comments below.
This article does not mention the most probable reason passwords are not auto-filled, and that is that the extension has not been added to the browser, which was the cause in my case. It’s not enough to just install LastPass on your computer, you have to add the extension to your browsers as well to implement auto-fill.
NOT EVERYONE DOWNLOADS THE APP. did not fix the issue. there should be multiple ways to assist with this that includes browser form not just the App

What worked for me (running Chrome on macOS Monterey v12.4) was to uninstall and reinstall the extension.
go to: chrome://extensions/
Remove Last Pass
go to: https://chrome.google.com/webstore/detail/lastpass-free-password-ma/hdokiejnpimakedhajhdlcegeplioahd
Add to Chrome
No. Pixel 3 with Android 12 & updated LP app. Even after granting permission for autofill service to LP (and no other apps), it won’t permit me to toggle on Android Oreo > Autofill, but I’m able to toggle on Legacy > Autofill.
I just got a new laptop with windows 11. Now my last pass won’t work. Can not launch with autofill. I’ve tried to get help with no avail. Is the problem the windows 11 or is it the laptop. I hate to go back to generating my own passwords, but I see no alternative.

Suggested fixes didn’t work for me, I do get around any site that won’t allow even cut and past by using my macro program which simulates typing anything in clipboard as if it is a HID (Hardware Input Device). I’ve always wondered why LastPass (LP) doesn’t function as a virtual HID device. I also agree there are some fields that LP can’t properly identify as the correct input location, I also tried to find what webpage was labeling the field name with no luck, this situation could be fixed by allowing the addition of Tab and Back Tab key strokes to the form fill information for example if you know on a given page the cursor always goes to a specific field the ability to add to tab strokes gets you to the correct field would be easy to implement. Example username password. I guess what I’m saying is if I can correct the issue with a macro LP should be able to do the same thing. In fairness there may be some unknown security reason these functions shouldn’t be implemented. What I can say is I never had any problem with LP .Just my 2 cents worth.

No. Probably done with Lastpass
I have the same issue on certain sites. The article is written as if they think we’re talking about it not entering the data on any site, not just a few. I believe some sites don’t name or label the fields properly or something like that so LastPass does not fill the data because it does not recognize the fields. I was trying to find an article that would help us identify the field names on a site and a way to add those custom fields to LastPass to autofill them instead of the normal username and password fields.
No. Several password sites dont auto load. One wont even let me use the manual fill.
Tried all suggestions, no luck.
What Brian said. The option to Reset cache in iOS settings for LastPass is misdescribed. You need to open LastPass and got to SETTINGS (not iOS settings) and from there go to ACTIONS, and there you can clear the local cache
Didn’t help there is no option in ipados to Reset cache on next startup
