My Node version is 10.15.0 and NPM version is 6.8.4 On running npm install after upgrading npm to 14.16.0 and npm to 7.6.2
Getting this error -
npm ERR! code E401

npm ERR! that means you likely typed your password in incorrectly.

Try Deleting the package-lock.json file before running the command "npm install" after upgrading the node versions, if you have not done that.
If that will not work try removing the.npmrc file in $HOME directory as mentioned in this post.

I had the same error with the company registry configured in .npmrc
registry=https:<company-registry-url>
Node version: 19.1.0
NPM version: 8.19.3
Solution:
Execute npm login
$ npm login
npm notice Log in on https:<registry-url>
Username: xxxx
Password:
Email: (this IS public) (xxxx)
Logged in as xxx on https:<registry-url>.
After this .npmrc
got updated with
//<registry-url>/:_authToken=xxxxx
Your password in.npmrc must be base64 encoded. Easy to screw up just copy-pasting the password, need to base64 encode that.
In the directory C/Users/your-windows-username/
delete the following files:
.cache
.package
.package-lock
.npmrc
After that, go to your project and run the following command in your terminal
npm i
Had the same issue with Node 16.xx I have done everything from this topic and those topics which were mentioned here and nothing helped me!
The only thing that helped me to login was that I have deleted Node 16.xx and installed Node 14.8.1 from here - https://nodejs.org/en/download/releases/
I have been getting the same error recently on various projects after running npm run dev
:
npm ERR! code E401
npm ERR! Incorrect or missing password.
What fixed it for me was to delete my package-lock.json
file (and any yarn.lock
files, which might create conflicts with npm) and the node_modules
directory. Then I updated my npm packages with npm update
. (CAUTION: Before updating any npm packages, you should probably create a new Git branch and run npm update
in that new branch. If you run into bigger problems after the updates, then you can revert back to your previous branch.)
After my packages were updated, then running my npm startup script (eg npm run dev
) worked again without errors.
NOTE: You can run npm outdated
to see which of your npm packages could use an update.
It can be happening because of a bug on npm. This was happening to me with npm v7. Switched to v6 and it worked.

Reinstall the lastest node.js. That fixed my issue.
