Please keep in mind the following if you do receive access again:
- A password manager can assist with holding onto passwords and creating complex passwords that are more difficult to hack by a 3rd party
- Recovery accounts and numbers are important to assist with the recovery process
- MFA can be vital to prevent compromise. Hope this helps. If you need further help on this, tag me in a comment. If the suggested response helped you resolve your issue, please 'Accept as answer', so that it can help others in the community looking for help on similar topics.
