## Questions & Answers

**Q: I currently use a Yubikey but this is a less expensive option. Will this work with lastpass?**
A: Does LastPass support FIDO/U2F authentication with Yubikey?

We currently do not.

Once FIDO/U2F is supported in all major browsers (the U2F standard is currently only supported by the Chrome browser, with Firefox support in beta), we will add LastPass support for this MFA. Please see the bug report for Firefox here - and post your request to add this support.

In the mean time, users can configure their keys to Mode 6 to work with both as mentioned here

If your key does not support an OTP mode, it will not currently work with LastPass.

**Q: I have two gmail accounts, how many fido sticks do i need to protect two gmail account. do i need to buy 2 ?**
A: you can use one key with multiple accounts

https://support.google.com/accounts/answer/6103543?hl=en

**Q: Is this company a known and reputable company for this type of security?**
A: So, I was trying to research this company. They have a website. That seems like it. I can't find Thetis on Linkedin (who is the CEO of Thetis?), they don't have any social media presence, their website has opaque domain registration. They AREN'T listed on the Fido Alliance website, as a lot of other FIDO keys are. I contacted them for support yesterday and haven't heard back (seen other people say the company is unresponsive). The more research I do, and the less info I find, the more nervous I am about using this product.

**Q: Does it work on android?**
A: Since this is a USB-A FOB, you would need an adapter that goes from USB-A to USB-C or Micro-USB, and there are no guarantees that with an adapter it will work. (Some do, and some don't.)
