This is happening with me as well. I tried different combinations of disabling/reenabling the FPR feature in lastpass vault, uninstalling/reinstalling binary support / native messaging, uninstalling/reinstalling standalone chrome plugin and uninstalling/reinstalling lastpass desktop.
The aforementioned workaround does work for me. Just to be clear, you've gotta click the second "LastPass" (it just says "LastPass").
Firefox works as it should. Just Chrome having the issue, and it is on all the PCs I use (different FPRs including USB ones like digitalpersona U.are.U 4500 and Kensington VeriMark USB, as well as built-in ones such as the ones on the ThinkPad x390 and T480s).
I have had this issue too, for about two months
As this seems to be an issue that the Devs are working on, I have found a work-around and posted it
With this work-around, I can get the LastPass Chrome extension to ask for the fingerprint again
Now when Chrome is closed it should close completely, and when it opens again is asks for the fingerprint.
This is not very satisfactory, but at least it seems to work
Our development team is aware of this issue and working on a resolution, although we do not have a date for an ETA to share currently. The workaround has been marked as a solution in the meantime so users can quickly find a workaround, and as soon as I have more news from our development team I will update this thread.
This workaround does not work for me (Version 88.0.4324.182 (Official Build) (64-bit) & Version 88.0.4324.190 (Official Build) (64-bit)). Did this workaround stop being viable for anyone else for more recent versions of Chrome? Unfortunately, I haven't been able to find another alternative.
