### Problem to solve The current `Profile / SSH Keys` datepicker is a [`input type="date"`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date) element. This causes the input to be inconsistent across different browsers: > The input UI generally varies from browser to browser The input also doesn't match the datepicker on `Profile / Personal Access Tokens` which uses the [`GlDatepicker`](https://gitlab-org.gitlab.io/gitlab-ui/?path=/story/base-datepicker--default) component. ### Screenshots | Current (SSH Keys) | [datepicker](https://gitlab-org.gitlab.io/gitlab-ui/?path=/story/base-datepicker--default) (Personal Access Tokens) | |---------|--------------------------------------------------------------------------------------------| |  |  | ### Proposed implementation Replace the `Profile / SSH Keys` datepicker with a [`GlDatepicker`](https://gitlab-org.gitlab.io/gitlab-ui/?path=/story/base-datepicker--default) component. ### Availability & Testing <!-- This section needs to be retained and filled in during the workflow planning breakdown phase of this feature proposal, if not earlier.
