No funciona bien con aplicaciones que tienen pop-up login.
No siempre está activa la aplicación.
En general es una buena aplicación pero cuesta activarla.

The app is buggy. After Sept. 16 2020 update I cannot log into the app on my PC, have to use a one time password half the time

All of this looks legitimate. However, as with Google and Facebook, LogMeIn seeks to combine information collected through the app with information about me which that company will collect FROM OTHER SOURCES. Even if it's mostly for app functionality and marketing purposes. I don't need any more advertising or spam than I already get!

This add-on doesn't stay with Firefox. Every time I open Firefox I have to re-download LastPass.

Works as advertised except one: I have 2FA activated and I am infuriated by constant re-authorization prompts, despite ticking to remember the browser. I am nagged at least once a day on all my browsers.

Doesn't remember masterpassword or remembers 2FA for 30 days when I check the box. This fails in Firefox for over one year now and doesn't get fixed.

Please fix the Android Extension. When you type your password and try to login nothing happens.
It would be a lot better to have the Firefox Mobile Extension working because the LastPass App is just not reliable in recognizing logins

Fantastic when it works, but it stops functioning properly every few weeks. I need to remove the extension and reinstall to get it working again.
