Hello @liviu.manolache.mli,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having with your account. Please verify if you have enabled the setting "Log out of other devices upon login from a different device". You can find it in your vault > Account Settings > Show Advanced Settings > Security. Please have it disabled and it should no longer occur.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
