Hello @viraltrending,
First things first: I can reassure you, these are not hacks of your accounts.
What you have received are not hacking attempts, but an information that you yourself have just tried to access your own account via a third party tool (Blog2Social). Since our servers are located in Germany (we are a German company and therefore have server locations in Cologne) these notifications inform you about it.
For all messages that you have listed, we also have corresponding entries in our FAQ:
1. Gmail- Someone just used your password to try to sign in to your account. / 3. Instagram – some one trying to login with your account in Germany
You can find the solution for this one right here: Google connection.
The same applies to Instagram: “How to auto post to Instagram directly from your blog”
2 . Pinterest- We noticed a login from a new device or location and want to make sure it’s you.
That’s the usual and obligatory security notification by Pinterest you get if you enabled the Two-factor Authentication. You should receive this notification, everytime you connect one of your WordPress solutions with Pinterest for the first time.
4. Twitter some is trying login account in Germany
That’s the usual and obligatory security notification by Twitter you get if you enabled the login confirmation in your Twitter settings. You should receive this notification, everytime you connect one of your WordPress solutions with Twitter for the first time.
If you have any further questions or would like to go through the registration process with us, you can also contact us personally by phone.
We would be very happy if you could reconsider your rating in view of this information.
