Norton Lifelock is what Symantec (parent company of Norton) rebranded itself to.
That said, this sort of email could be a fishing scam and why companies initially* moved to 2 factor authentication (2FA). They send tons of emails, you click the link to log in and fail, they now have an email and password you've used in the past, possibly with that company, they can then use those credentials to log into that site, or better still, use a pass through. They did this to one of the first banks to implement 2FA claiming it was foolproof, I believe it was Bank of America (BofA). How it worked was you went to a scam site/domain linked in the email which loaded BofA in the background and you put your credentials into the fake site which put them into BofA, including the 2fa code you entered and told you it failed, running you in circles while it drained your account. This is why you never click email links before logging in, ESPECIALLY IF YOU USE Microsoft products (F-U Microsoft for hiding extensions and links you incompetent morons!), go to the website you know is the right one then log in.
*2FA can work if used properly but it rarely actually is, in reality it's nearly useless and mostly a scam.
Not only are many companies are using it for data harvesting under the guide or security, but if you are using a phone to log in, and they send you 2FA key to said phone you just destroyed the whole point of having a 2nd factor. The second factor needs to be a secondary system completely disconnected from the first in order to actually work. Worse still, why in god's name would you use the device you log in with and the most easily stolen thing you posses being used as your 2 factor?
And have you ever lost your phone and had to rest your 2FA on an account, what an absolute nightmare. I had an update that wiped my phone (it had an issue), to reset my 2FA on a bank account they wanted to place a 2 week(!) hold on my money. Luckily I had a secondary "key" to bypass the 2fa and reset it without a 2 week wait but not all companies do this. When i created those keys I forgot I even had them and had to get with support before I even realized I had them at all since the account was so old.
Some companies also lead you in circles, you can't change email without a 2fa, but you can't create a 2fa without a working email on the account, so if you rejected using 2fa your account was effectively screwed if you lost access to that email account. This happened to me with a gaming account.
