SeleID HelpKeeping access to your confirmed account email is one of the simplest ways to protect your SeleID. A trusted backup address can provide another contact option where the account screen supports it, but adding an address is not the same as proving ownership.
Review the current address
Open Account Recovery from the Security Center. Check the account email and confirmation status displayed. If you need to replace the main address, read changing your email first. Do not enter someone else's inbox because they offered to help.
Add a backup only through the available controls
If a Backup email section is visible, enter an address you control and follow its send-and-confirm steps. The current shared screen requests a six-digit code for that address. Use the code privately and wait for a confirmed status. A pending address has not completed verification.
Understand what it changes
A confirmed backup address does not automatically become your main sign-in email or guarantee that every recovery flow can use it. Password reset still asks for the account email shown in the relevant sign-in flow. If you cannot use the offered method, follow account recovery or contact support.
Keep it healthy
Secure both inboxes, review old addresses and update them before losing access. Never share mailbox passwords or recovery codes. Combine these habits with two-step verification where supported.
