If you’re sure your password is correct, here are the most common reasons:
Two-factor authentication (2FA)
LinkedIn may require an additional approval step.
What to do:
Check your email
Check your phone (SMS)
Check your LinkedIn app notifications
Approve the login, then try again
If you don't have any verification code OR if the code doesn't work :
try again after 5-10 minutes
desactivate the 2FA on your LinkedIn account and try again
Temporary LinkedIn restriction
Sometimes LinkedIn blocks new logins temporarily.
What to do:
Wait 15–30 minutes
Try again later
Avoid repeated attempts
Session conflict
Too many active LinkedIn sessions can cause errors.
What to do:
Log out of LinkedIn everywhere
Restart your browser
Retry the connection
